Not Solid Yet; Solid State Batteries Have 50% Greater Energy Density, More Range. Lower Cost, Lighter, & Faster Charge Time But Battery Packs For Cars Are Far From Ready Even With Big Promise

Things are not solid yet with solid state batteries for EVs.
Solid-state batteries promise to offer greater energy density compared to lithium batteries.
Not yet being used in the production of mass-market cars ’til at least 2023;
Companies are mostly working on the technology of solid state batteries at the cell level.
And the batteries are expected to be significantly higher priced than lithium-ion.
Ford & BMW led a $130M Series B investment round in solid-state battery startup. So this is the future.
