Fisker, the electric vehicle car company that will be showcasing its flagship EMotion vehicle at the CES Show January 9-12 in Las Vegas, has filed patents for a revolutionary battery. The patent has been filed under a non-publication request, but some details are known.
The batteries are solid state and feature 3-dimensional electrodes as shown in the illustration above. The twist on the electrodes provides 2.5 times the energy density of other batteries, and 25 times more surface, which improves conductivity and enables fast charging and cold temperature operation.
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 anticipates the technology to be automotive production grade ready from 2023 onwards.
Dr. Fabio Albano is VP of Battery Systems at Fisker and was part of the team that developed the first solid state lithium-ion batteries at Sakti13, now owned by Dyson of vacuum fame. Dr. Albani’s comments from the press release:
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.
While there is much excitement about the breakthrough, it is tempered with some skepticism. Mashable says “The company is still touting an unprecedented 400-mile range for its lithium-ion battery configuration, but so far Fisker hasn’t yet provided anything to back up its specs — the $130,000 EMotion hasn’t made any public appearances.”
Electrek’s take starts with these comments: “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.”
