Donut Lab’s solid-state battery could barely hold a charge after getting damaged

Donut Lab conducted damage testing on its solid-state battery, revealing that while the damaged battery could barely hold a charge, it importantly did not catch fire. This follows previous testing issues where the battery's pouch lost its vacuum seal during extreme heat tests. The company views the non-flammable result as a significant safety victory despite the poor charge retention.

Background

Solid-state batteries are considered the next generation of energy storage technology, promising higher energy density and improved safety compared to traditional lithium-ion batteries. Donut Lab is among several companies racing to commercialize this technology.
