Donut Lab is on a mission to prove to the world its solid-state battery is real, one independent test at a time. We've seen speed charging tests, extreme heat tests, and not-a-supercapacitor tests. Today's test is to see how the battery hold up under damage. The results: while it could barely sustain a charge, it didn't burst into flames, which Donut Lab sees as a victory. If you'll recall, during the extreme heat tests, the pouch surrounding Donut's battery lost its vacuum seal. This led to researchers at Finland's state-owned VTT Technical Research Centre, which conducted all of the lab's previous tests, to explore whether the cell could …Read the full story at The Verge.
