Energy Storage Technologies vie for Investment and Market Share – “And the Winners Are” …


One of the conveniences that makes fossil fuels hard to phase out is the relative ease of storing them, something that many of the talks at Advanced Energy Materials 2018 aimed to tackle as they laid out some of the advances in alternatives for energy storage.

Max Lu during the inaugural address at AEM 2018

“Energy is the biggest business in the world,” Max Lu, president and vice-chancellor of the University of Surrey, told attendees of Advanced Energy Materials 2018 at Surrey University earlier this month. But as

Lu, who has held numerous positions on senior academic boards and government councils, pointed out, the shear scale of the business means it takes time for one technology to replace another.

“Even if solar power were now cheaper than fossil fuel, it would be another 30 years before it replaced fossil fuel,” said Lu. And for any alternative technology to replace fossil fuels, some means of storing it is crucial.

Batteries beyond lithium ion cells

Lithium ion batteries have become ubiquitous for powering small portable devices.

But as Daniel ShuPing Lau, professor and head at Hong Kong Polytechnic University, and director of the University Research Facility in Materials pointed out, lithium is rare and high-cost, prompting the search for alternatives.

He described work on sodium ion batteries, where one of the key challenges has been the MnO2 electrode commonly used, which is prone to acid attack and disproportionation redox reactions.

Lau described work by his group and colleagues to get around the electrode stability issues using environmentally friendly K-birnessite MnO2 (K0.3MnO2) nanosheets, which they can inkjet print on paper as well as steel.

Their sodium ion batteries challenge the state of the art for energy storage devices with a working voltage of 2.5 V, maximum energy and power densities of 587 W h kgcathode−1 and 75 kW kgcathode−1, respectively, and a 99.5% capacity retention for 500 cycles at 1 A g−1.

Metal air batteries are another alternative to lithium-ion batteries, and Tan Wai Kan from Toyohashi University of Technology in Japan described the potential of using a carbon paper decorated with Fe2O3 nanoparticles in a metal air battery.

They increase the surface area of the electrode with a mesh structure to improve the efficiency, while using solid electrolyte KOHZrO2 instead of a liquid helped mitigate against the stability risks of hydrogen evolution for greater reliability and efficiency.

A winning write off for pseudosupercapacitors

Other challenges aside, when it comes to stability, supercapacitors leave most batteries far behind.

Because there is no mass movement, just charge, they tend to stay stable for not just hundreds but hundreds of thousands of cycles

They are already in use in the Shanghai bus system and the emergency doors on some aircraft as Robert Slade emeritus professor of inorganic and materials chemistry at the University of Surrey pointed out.

He described work on “pseudocapacitance”, a term popularised in the 1980s and 1990s to to describe a charge storage process that is by nature faradaic – that is, charge transport through redox processes – but where aspects of the behaviour is capacitive.

MnO2 is well known to impart pseudocapacitance in alkaline solutions but Slade and his colleagues focused on MoO3.

Although MnO3 is a lousy conductor, it accepts protons in acids to form HMoO, and exploiting the additional surface area of nanostructures further helps give access to the pseudocapacitance, so that the team were able to demonstrate a charge-discharge rate of 20 A g-1 for over 10,000 cycles.

This is competitive with MnO2 alkaline systems. “So don’t write off materials that other people have written off, such as MoO3, because a bit of “chemical trickery” can make them useful,” he concluded.

Down but not out for solid oxide fuel cells

But do we gain from the proliferation of so many different alternatives to fossil fuels? According to John Zhu, professor in the School of Chemical Engineering at the University of Queensland in Australia, “yes.”

For clean energy we need more than one solution,” was his response when queried on the point after his talk.

In particular he had a number of virtues to espouse with respect to solid oxide fuel cells (SOFCs), which had been the topic of his own presentation.

Besides the advantage of potential 24-7 operation, SOFCs generate the energy they store. As Zhu pointed out, “With a battery energy the source may still be dirty – so you are just moving the pollution from a high population density area to a low one.”

In contrast, an SOFC plant generates electricity directly from oxidizing a fuel, while at the same time it halves the CO2 emission of a coal-based counterpart, and achieves an efficiency of more than 60%.

If combined with hot water generation more than 80% efficiency is possible, which is double the efficiency of a conventional coal plant. All this is achieved with cheap materials as no noble metals are needed.

Too good to be true? It seemed so at one point as promising corporate ventures plummeted, one example being Ceramic Fuel Cells Ltd, which was formed in 1992 by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and a consortium of energy and industrial companies.

After becoming ASX listed in 2004, and opening production facilities in Australia and Germany, it eventually filed voluntary bankruptcy in 2015.

So “Are SOFCs going to die?” asked Zhu.

So long as funding is the lifeline of research apparently not, with the field continuing to attract investment from the US Department of Energy – including $6million for Fuel Cell Energy Inc. Share prices for GE Global Research and Bloom Energy have also doubled in the two months since July 2018, but Zhu highlights challenges that remain.

At €25,000 to install a 2 kW system he suggests that cost is not the issue so much as durability. While an SOFC plant’s lifetime should exceed 10 years, most don’t largely due to the high operating temperatures of 800–1000 °C, which lead to thermal degradation and seal failure. Lower operating temperatures would also allow faster start up and the use of cheaper materials.

The limiting factor for reducing temperatures is the cathode material, as its resistance is too high in cooler conditions. Possible alternative cathode materials do exist and include – 3D heterostructured electrodes La3MiO4 decorated Ba0.5Sr0.3Ce0.8Fe0.3O3 (BSCF with LN shell).

Photocatalysts all wrapped up

Other routes for energy on demand have looked at water splitting and CO2 reduction.

As Lu pointed out in his opening remarks, the success of these approaches hinge on engineering better catalysts, and here Somnath Roy from the Indian Institute of Technology Madras, in India, had some progress to report.

“TiO2 is to catalysis what silicon is to microelectronics,” he told attendees of his talk during the graphene energy materials session. However the photocatalytic activity of TiO2 peaks in the UV, and there have been many efforts to shift this closer to the visible as a result.

Building on previous work with composites of graphene and TiO2 he and his colleagues developed a process to produce well separated (to allow reaction space) TiO2 nanotubes wrapped in graphene.

Although they did not notice a wavelength shift in the peak catalytic activity to the visible due to the graphene, the catalysis did improve due to the effect on hole and electron transport.

There was no shortage of ideas at AEM 2018, but as Lu told attendees,

“Ultimately uptake does not depend on the best technology but the best return on investment.”

Speaking to Physics World  he added,

“The route to market for any energy materials will require systematic assessment of the technical advantages, market demand and a number of iterations of property-performance-system optimization, and open innovation and collaboration will be the name of the game for successful translation of materials to product or processes.”

Whatever technologies do eventually stick, time is of the essence. Most estimates place the tipping point for catastrophic global warming at 2050.

Allowing 30 years for the infrastructure overhaul that could allow alternative energies to totally replace fossil fuels leaves little more than a year for those technologies to pitch “the best return on investment”.

Little wonder advanced energy materials research is teaming.

Our investment in Lucid is a strong example of these objectives.”

A*STAR team uses graphene oxide to create a cathode for improved li-ion batteries


A*STAR researchers have found that incorporating organic materials into lithium ion batteries could lower their cost and make them more environmentally friendly. The team has developed an organic-based battery cathode that has significantly improved electrochemical performance compared to previous organic cathode materials. The new material is also robust, remaining stable over thousands of battery charge/discharge cycles.

An electron-deficient, rigid organic molecule called hexaazatrinaphthalene (HATN) was previously investigated as an organic cathode material for lithium ion batteries. However, its promising initial performance declined rapidly during use, because the molecule began to dissolve into the battery’s liquid electrolyte. A new cathode material, in which HATN was combined with graphene oxide in an attempt to prevent the organic material from dissolving, has now been developed by Yugen Zhang and his colleagues from the A*STAR Institute of Bioengineering and Nanotechnology.

“Graphene oxide has excellent electronic conductivity, and surface oxygen functionality that may form hydrogen-bonding interactions with HATN,” Zhang says. He explains that this made graphene oxide a promising candidate for forming a HATN-graphene oxide nanocomposite.

The nanocomposite’s performance reportedly exceeded expectations. The materials combined to form core-shell nanorods in which the HATN was coated with graphene oxide. “Graphene oxide and HATN formed a very nice composite structure, which solved the dissolution issue of HATN in electrolyte and gave the cathode very good cycling stability,” Zhang says. A lithium ion battery using this material as its cathode retained 80% of its capacity after 2000 charge/discharge cycles.

The team saw even better performance when they combined graphene oxide with a HATN derivate called hexaazatrinaphthalene tricarboxylic acid (HATNTA). A battery made from this material retained 86% of its capacity after 2,000 charge/discharge cycles. The improved performance is probably due to the polar carboxylic acid groups on the HATNTA molecule, which attached the molecule even more strongly to the graphene oxide.

The team is continuing to develop new materials to improve the performance of organic cathodes, Zhang says. Aside from investigating alternatives to graphene oxide, the team also is working on HATN-based porous polymers for use as organic cathode materials, which should enhance the flow of ions during battery charge and discharge.

This graphene battery can recharge itself to provide unlimited clean energy


Scientists are exploring graphene’s ability to ‘ripple’ into the third dimension.

Graphene is a modern marvel. It is comprised of a single, two-dimensional layer of carbon, yet is 200 times stronger than steel and more conductive than any other material, according to the University of Manchester, where it was first isolated in 2004.

Graphene also has multiple potential uses, including in biomedical applications such as targeted drug delivery, and for improving the lifespan of smartphone batteries.

Now, a team of researchers at the University of Arkansas has found evidence to suggest graphene could also be used to provide an unlimited supply of clean energy.

The team says its research is based on graphene’s ability to “ripple” into the third dimension, similar to waves moving across the surface of the ocean. This motion, the researchers say, can be harvested into energy.

To study the movement of graphene, lead researcher Paul Thibado and his team laid sheets of the material across a copper grid that acted as a scaffold, which allowed the graphene to move freely.

Thibado says graphene could power biomedical devices such as pacemakers.

The researchers used a scanning tunnelling microscope (STM) to observe the movements, finding that narrowing the focus to study individual ripples drew clearer results.

In analysing the data, Thibado observed both small, random fluctuations, known as Brownian motion, and larger, coordinated movements.

As the atoms on a sheet of graphene vibrate in response to the ambient temperature, these movements invert their curvature, which creates energy, the researchers say.

Harvesting energy

“This is the key to using the motion of 2D materials as a source of harvestable energy,” Thibado says.

“Unlike atoms in a liquid, which move in random directions, atoms connected in a sheet of graphene move together. This means their energy can be collected using existing nanotechnology.”

The pieces of graphene in Thibado’s laboratory measure about 10 microns across (more than 20,000 could fit on the head of a pin). Each fluctuation exhibited by an individual ripple measures only 10 nanometres by 10 nanometres, and could produce 10 picowatts of power, the researchers say.

As a result, each micro-sized membrane has the potential to produce enough energy to power a wristwatch, and would never wear out or need charging.

Thibado has created a device, called the Vibration Energy Harvester, that he claims is capable of turning this harvested energy into electricity, as the below video illustrates.

This self-charging power source also has the potential to convert everyday objects into smart devices, as well as powering more sophisticated biomedical devices such as pacemakers, hearing aids and wearable sensors.

Thibado says: “Self-powering enables smart bio-implants, which would profoundly impact society.”

New super-battery that doesn’t catch fire described as a ‘paradigm shift’


The latest rechargeable battery technology could drastically improve the capabilities of mobile phones and electric vehicles.

It seems that nearly every household electronic item these days requires a lithium-ion rechargeable battery, from a vacuum cleaner to a pair of headphones.

This results in many of us having a multitude of different devices hooked up to various chargers at any given time, which isn’t exactly ideal.

Now, however, a team of scientists from the University of Michigan is heralding a major breakthrough that could drastically increase the power of rechargeable batteries, with the added bonus of not catching on fire.

Existing rechargeable batteries are made from lithium-ion, a technology that enables a quick charge but has the massive drawback of its exposure to open air causing it to explode and catch fire. It also requires regular charging and can degrade quickly due to overcharging.

But, in a paper soon to be published to the Journal of Power Sources, the research team describe how by using a ceramic, solid-state electrolyte, it was able to harness the power of lithium-metal batteries without any of the traditional negatives of lithium-ion.

In doing so, it could double the output of batteries, meaning a phone could run for days or weeks without charging, or an electric vehicle (EV) could rival fossil fuel-powered cars in range.

Jeff Sakamoto, leader of the research team, said: “This could be a game-changer, a paradigm shift in how a battery operates.”

In the 1980s, lithium-metal batteries were seen as the future, but their tendency to combust during charging led researchers to switch to lithium-ion.

10 times the charging speed

These batteries replaced lithium metal with graphite anodes, which absorb the lithium and prevent tree-like filaments called dendrites from forming, but also come with performance costs.

For example, graphite has a maximum capacity of 350 milliampere hours per gram (mAh/g), whereas lithium metal in a solid-state battery has a specific capacity of 3,800 mAh/g.

To get around the ever so problematic exploding problem in lithium-metal batteries, the team created a ceramic layer that stabilises the surface, keeping dendrites from forming and preventing fires.

With some tweaking, chemical and mechanical treatments of the ceramic provided a pristine surface for lithium to plate evenly.

Whereas once it would take a lithium-metal EV up to 50 hours to charge, the team said it could now do it in three hours or less.

“We’re talking a factor of 10 increase in charging speed compared to previous reports for solid-state lithium-metal batteries,” Sakamoto said.

“We’re now on par with lithium-ion cells in terms of charging rates, but with additional benefits.”

Sodium-ion Batteries Could Get Better Thanks to Graphene and Lasers


You hear a lot about the shortcomings of lithium-ion batteries, mostly related to the slow rate of capacity improvements. However, they’re also pretty expensive because of the required lithium for cathodes. Sodium-ion batteries have shown some promise as a vastly cheaper alternative, but the performance hasn’t been comparable. With the aid of lasers and graphene, researchers may have developed a new type of sodium-ion battery that works better and could reduce the cost of battery technology by an order of magnitude.

The research comes from King Abdullah University of Science and Technology (KAUST) in Saudi Arabia. Much of the country’s water comes from desalination, so there’s a lot of excess sodium left over. Worldwide, sodium is about 30 times cheaper than lithium, so it would be nice if we could use that as a battery cathode. The issue is that standard graphite anodes don’t hold onto sodium ions as well as they do lithium.

The KAUST team looked at a way to create a material called hard carbon to boost sodium-ion effectiveness. Producing hard carbon usually requires a complex multi-step process that involves heating samples to more than 1,800 degrees Fahrenheit (1,000 Celsius). That effectively eliminates the cost advantage of using sodium in batteries. The KAUST team managed to create something like hard carbon with relative ease using graphene and lasers.

It all starts with a piece of copper foil. The team applied a polymer layer composed of urea polymides. Researchers blasted this material with a high-intensity laser to create graphene by a process called carbonization. Regular graphene isn’t enough, though. While the laser fired, nitrogen was added to the reaction chamber. Nitrogen atoms end up integrated into the material, replacing some of the carbon atoms. In the end, the material is about 13 percent nitrogen with the remainder carbon.

Making anodes out of this “3D graphene” material offers several advantages. For one, it’s highly conductive. The larger atomic spacing makes it better for capturing sodium ions in a sodium-ion battery, too. Finally, the copper base can be used as a current collector in the battery, saving additional fabrication steps.

The researchers tested a sodium-ion battery with 3D graphene anodes, finding the system outperformed existing sodium-ion systems.

It’s still not as potent as lithium-ion, but these lower cost cells could become popular for applications where high-performance lithium-ion tech isn’t necessary. Your phone will run on lithium batteries for a bit longer.

Self-heating, fast-charging batteries could speed up EV adoption

A barrier to universal adoption of electric vehicles (EVs) has to do with charging the battery. It can take anywhere from a half hour up to 12 hours, depending on the charging point used and the EV’s battery capacity.

And of course, there needs to be a massive charging infrastructure in place so that drivers will feel confident driving long distances on a single charge.

One factor that significantly impacts EV driving range is the outside temperature. According to the Office of Energy Efficiency & Renewable Energy, cold weather can affect the driving range of plug-in EVs by more than 25%. In a project at Idaho National Laboratory, researchers found that plug-in hybrid electric Chevy Volts driven in winter in Chicago had 29% less range than those driven in spring in Chicago.

It’s common knowledge that batteries, in general, don’t do well in freezing temperatures. But if we’re ever to move beyond gas-powered vehicles, we need a battery that can charge quickly, hold its charge in cold weather, and not cost an arm and a leg.

Researchers at Pennsylvania State University have been thinking about this for a while. A little over two years ago, William E. Diefenderfer Chair of mechanical engineering, professor of chemical engineering, and professor of materials science and engineering and director of the Electrochemical Engine Center,  Chao-Yang Wang and his team developed a self-heating lithium battery that uses thin nickel foil with one end attached to the negative terminal and the other end extending outside the battery, creating a third terminal.

The foil serves as a heater of sorts. A temperature sensor sets off electron flow through the foil—heating it up and warming the battery. The sensor switches off after the battery reaches 32oF, allowing electric current to continue flowing normally.

Now, Wang and his team have taken their technology a step further by enabling the battery to charge itself in 15 minutes at temperatures as low as –45oF.

When the battery’s internal temperature reaches room temperature and above, the switch opens to allow electric current to flow in and quickly charge the battery.

“One unique feature of our cell is that it will do the heating and then switch to charging automatically,” Wang explains in a Penn State news release.

He says their battery would not affect the current charging infrastructure. “Also, the stations already out there do not have to be changed,” he adds. “Control of heating and charging is within the battery, not the chargers.”

According to the researchers, charging a lithium-ion battery quickly at temperatures under 50 degrees contributes to its degradation and lithium plating—which can make a battery unsafe. Long, slow charging at 50oF, they say, can avoid lithium plating.

And Wang says their technology can work for other batteries as well.

“The self-heating battery structure is also essential for all solid-state ceramic batteries because it thermally stimulates uniform lithium deposition at the lithium metal anode and compensates for insufficient ionic conductivity of ceramic or glass electrolytes,” he explains in an email. “Plus, solid-state batteries are inherently safe and more efficient to operate at high temperatures. Indeed, a solid state battery would be much inferior without the self-heating battery structure.”

He also says their technology is “pretty mature and readily commercialized by auto OEMs and battery manufacturers.”

That’s good news for those of us who have been hesitant to trade in our gas-powered vehicles for electric ones.

The paper, published in Proceedings of the National Academy of Sciences of the United States of America, is “Fast charging of lithium-ion batteries at all temperatures” (DOI: 10.1073/pnas.1807115115).

 

A Failed Car Company Gave Rise to a Revolutionary New Battery – “Fisker’s Folly” Or “Henrik’s Home-Run”?


Fisker’s solid-state battery powers electric vehicles–and drones and flying taxis.

Since Alessandro Volta created the first true battery in 1800, improvements have been relatively incremental.

When it comes to phones and especially electric vehicles, lithium-ion batteries have resisted a slew of efforts to increase their power and decrease the time it takes to charge them.

Henrik Fisker, known for his high-end sports-car design, says his Los Angeles-based company, Fisker Inc., is on the verge of a breakthrough solid-state battery that will give EVs like his sleek new EMotion an extended range and a relatively short charging period.

“With the size of battery pack we have made room for, we could get as much as a 750-kilometer [466-mile] range,” he says. The same battery could reduce charging time to what it currently takes to fill your car with gas.

Traditional lithium-ion batteries, like all others, use a “wet” chemistry– involving liquid or polymer electrolytes–to generate power.

But they also generate resistance when working hard, such as when they are charging or quickly discharging, which creates heat. When not controlled, that heat can become destructive, which is one reason EVs have to charge slowly.

Solid-state batteries, as the name implies, contain no liquid. Because of this, they have very low resistance, so they don’t overheat, which is one of the keys to fast recharging, says Fisker.

But their limited surface area means they have a low electrode-current density, which limits power. Practically speaking, existing solid-state batteries can’t generate enough juice to push a car. Nor do they work well in low temperatures. And they can’t be manufactured at scale.

Fisker’s head battery scientist, Fabio Albano, solved these problems by essentially turning a one-story solid-state battery into a multistory one.

“What our scientists have created is the three-dimensional solid-state battery, which we also call a bolt battery,” says Fisker. “They’re thicker, and have over 25 times the surface that a thin-film battery has.

That has allowed us to create enough power to move a vehicle.” The upside of 3-D is that Fisker’s solid-state battery can produce 2.5 times the energy density that lithium-ion batteries can, at perhaps a third of the cost.

Fisker was originally aiming at 2023 production, but its scientists are making such rapid advances that the company is now targeting 2020.

“We’re actually ahead of where we expected to be,” Fisker says. “We have built batteries with better results quicker than we thought.” The company is setting up a pilot plant near its headquarters.

Solid state, however, isn’t problem free. Lower resistance aids in much faster charging, up to a point. “We can create a one-minute charge up to 80 percent,” Fisker says. “It all depends on what we decide the specific performance and chemistry of the battery should be.”

If a one- or two- or five-minute charge gives a driver 250 miles and handles the daily commute, that can solve the range-anxiety issue that has held back EV sales.

Solid-state-battery technology can go well beyond cars. Think about people having a solid-state battery in their garage that could charge from the grid when demand is low, so they don’t pay for peak energy, and then transfer that energy to their car battery. It could also act as an emergency generator if their power goes down. “This is nonflammable and very light,” says Fisker. “It’s more than twice as light as existing lithium-ion batteries. It goes into drones and electric flying taxis.”

Like many designers, Fisker is a bit of dreamer. But he’s also a guy with a track record of putting dreams into motion.

Joy ride.

Henrik Fisker’s car company crashed in the Great Recession, but one of the industry’s flashiest designers quickly got in gear again. His latest piece of automotive art: the EMotion.

Fisker has never created an automobile that didn’t evoke a response. He’s one of the best-known designers in the industry, with mobile masterpieces such as the Fisker Karma, the Aston Martin DB9, and the BMW Z8. It’s only appropriate his latest vehicle has been christened the EMotion.

The curvy, carbon fiber and aluminum all-wheel-drive EV, with its too-cool butterfly doors and cat’s-eye headlights, debuted at the Consumer Electronics Show in January. It will be the first passenger-vehicle offering of the new Fisker Inc.–the previous Fisker Automotive shuttered in 2013, in the aftermath of the Great Recession. (Reborn as Karma Automotive, that company makes the Revero, based on a Fisker design.)

Fisker ran out of funding but not ideas. He quickly got the new company going and has described the EMotion as having “edgy, dramatic, and emotionally charged design/ proportions–complemented with technological innovation that moves us into the future.” The car will come equipped with a Level 4 autonomous driving system, meaning it’s one step away from being completely autonomous.

You might want to drive this one yourself, though. The EMotion sports a 575-kw/780-hp- equivalent power plant that delivers a 160-mph top speed, and goes from 0 to 60 in three seconds. The sticker price is $129,000; the company is currently taking refundable $2,000 deposits.

Though designed to hold the new solid-state battery, the EMotion that will hit the road in mid-2020 has a proprietary battery module from LG Chem that promises a range of 400 miles — Tesla Model S boasts 335. About his comeback car, Fisker says he felt free to be “radically innovative.” For a niche car maker, it might be the only way to remain competitive.

Are Sustainable Super-capacitors from Wood (yes w-o-o-d) the Answer for the Future of Energy Storage? Researchers at UST China Think ‘Nano-Cellulose’ may Hold the Key


Supercapacitors are touted by many as the wave of the future when it comes to battery storage for everything from cell phones to electric cars.

Unlike batteries, supercapacitors can charge and discharge much more rapidly — a boon for impatient drivers who want to be able to charge their electric cars quickly.

The key to supercap performance is electrodes with a large surface area and high conductivity that are inexpensive to manufacture, according to Science Daily.

Carbon aerogels satisfy the first two requirements but have significant drawbacks. Some are made from phenolic precursors which are inexpensive but not environmentally friendly. Others are made from  graphene and carbon nanotube precursors but are costly to manufacture.

Researchers at the University of Science and Technology of China have discovered a new process that is low cost and sustainable using nanocellulose, the primary component of wood pulp that gives strength to the cell walls of trees.

Once extracted in the lab, it forms a stable, highly porous network which when oxidized forms a micro-porous hydrogel of highly oriented cellulose nano-fibrils of uniform width and length.

Like most scientific research, there was not a straight line between the initial discovery and the final process.

A lot of tweaking went on in the lab to get things to work just right. Eventually, it was found that heating the hydrogel in the presence of para-toluenesulfonic acid, an organic acid catalyst, lowered the decomposition temperature and yielded a “mechanically stable and porous three dimensional nano-fibrous network” featuring a “large specific surface area and high electrical conductivity,” the researchers say in a report published by the journal Angewandte Chemie International.

The chemists have been able to create a low cost, environmentally friendly wood-based carbon aerogel that works well as a binder-free electrode for supercapacitor applications with electro-chemical properties comparable to commercial electrodes currently in use.

Now the hard work of transitioning this discovery from the laboratory to commercial viability will begin. Contributed by Steve Hanley
