Solid Power’s solid-state batteries contain no liquid electrolyte. Instead, they are comprised of proprietary inorganic materials producing a product with higher energy density, without volatile or flammable components.
Solid State batteries provide substantially higher energy than conventional lithium ion (2-3X greater) while also enabling lower cost systems due to the potential for eliminating many of the costly safety features typically associated with lithium-ion systems.
Fisker claims the batteries would cost about one-third as much as li-ion ones.
In 2017, Toyota announced plans to have solid-state batteries in electric cars by 2020, while the Dyson electric car could also use solid-state battery technology developed by Sakti3.
