Representation of the three-dimensional electrodes:
When Henrik Fisker relaunched its electric car startup last year, he announced that their first car will be powered by a new graphene-based hybrid supercapacitor technology, but he later announced that they put those plans on the backburner and instead will use more traditional li-ion batteries.
Now the company is announcing a “breakthrough” in solid-state batteries to power their next-generation electric cars and they are filing for patents to protect their IP.
Get ready for some crazy claims here.
Solid-state batteries are thought to be a lot safer than common li-ion cells and could have more potential for higher energy density, but they also have limitations, like temperature ranges, electrode current density, and we have yet to see a company capable of producing it in large-scale and at an attractive price point competitive with li-ion.
Now Fisker announced that they are patenting a new solid-state electrode structure that would enable a viable battery with some unbelievable specs.
Here’s what they claim (via GreenCarCongress):
“Fisker’s solid-state batteries will feature three-dimensional electrodes with 2.5 times the energy density of lithium-ion batteries. Fisker claims that this technology will enable ranges of more than 500 miles on a single charge and charging times as low as one minute—faster than filling up a gas tank.”
Fisker has been all over the place with its new Emotion electric car and we have highlighted that in our look at Fisker’s unbelievable claims.
But its latest solid-state project is led by Dr. Fabio Albano, VP of battery systems at Fisker and the co-founder of Sakti3, which adds credibility to the effort.
Albano commented on the announcement:
“This breakthrough marks the beginning of a new era in solid-state materials and manufacturing technologies. We are addressing all of the hurdles that solid-state batteries have encountered on the path to commercialization, such as performance in cold temperatures; the use of low cost and scalable manufacturing methods; and the ability to form bulk solid-state electrodes with significant thickness and high active material loadings. We are excited to build on this foundation and move the needle in energy storage.”
Like any battery breakthrough announcement, it should be taken with a grain of salt. Most of those announcements never result in any kind of commercialization.
For this particular technology, Fisker says that it will be automotive production grade ready around 2023.
A lot of things can happen over the next 5 years.
In the meantime, Fisker plans to launch its Emotion electric car at CES 2018 in just 2 months.
Fisker has filed patents for solid-state batteries
It seems that we’re on the cusp of a solid-state battery revolution. The latest company to announce progress in developing the new type of battery is Fisker. It has filed patents for solid-state lithium-ion batteries and it expects the batteries to be produced on a mass scale around 2023.
Though Fisker is a very small car company that is currently taking deposits for its upcoming EMotion electric sedan, there are reasons to believe that the company could fulfill this promise. One of the members of the battery-development team was a co-founder of Sakti3, a company that formed to develop new batteries and announced its research into solid-state technology back in 2011. That company was purchased by Dyson, the vacuum cleaner company, which also intends on producing electric carsthat AutoExpress reports will feature solid-state batteries in 2020. Toyota is also expected to have solid-state batteries just ahead of Fisker around 2022.
The reason all these companies are working on developing solid-state batteries is because they present a whole host of advantages over what you’ll find in today’s phones, computers and cars. The two big ones are greater energy density and rapid charging times. Fisker claims the batteries it’s developing have an energy density 2.5 times that of current batteries, and they should be capable of providing a 500-mile driving range. The company also says the batteries could be recharged in as little as a minute. Both claims are similar to past claims from others, including Sakti3. Other benefits include lower estimated cost than conventional lithium-ion batteries as well as very little risk of fires or explosions.
Fisker also announced that it will display the new battery technology at the Consumer Electronics Show in January. It will be on display along with a close-to-production EMotion, which will be using more conventional lithium-ion batteries from LG Chem. That car has its own impressive claims with a range of more than 400 miles and the ability to regain around 125 miles of range in about 9 minutes. It will also retail for around $130,000, and the company is taking $2,000 reservations now. Fisker intends for it to go into production in 2019.
