The battery chemistry that could finally kill range anxiety

Solid-state cells have been '5 years away' for a decade. Here's what's actually changed. Manufacturing techniques borrowed from semiconductor fabs, rather than traditional battery plants, are finally solving the dendrite problem that killed earlier attempts.

The first commercial cells are smaller and more expensive than lithium-ion, but the trajectory — and the manufacturing partnerships now being announced — suggest this is the decade it stops being a lab demo.
