Solid-state EV batteries hit a milestone in the US – Factorial Energy launches first commercial program, cells promise 500-600+ miles of range with 40% weight savings

Submission Statement: Solid-state batteries have been “just around the corner” for years, but Factorial’s partnership with Karma marks the first time a US company has moved from lab prototypes to an actual commercial vehicle program. The real game-changer here is compatibility with 80% of existing lithium-ion manufacturing equipment, meaning we won’t need billions in entirely new factory buildouts to scale this up. If these cells deliver on the 500-600 mile range promise with 40% weight savings, it could fundamentally shift EV adoption by making range anxiety a non-issue. Mercedes already drove a modified EQS over 745 miles on a single charge using Factorial’s cells, so the tech clearly works outside the lab.

So not solid-state. Another misleading headline
