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

"Donut Lab is on a mission to prove to the world its solid-state battery is real, one independent test at a time. Today's test is to see how the battery holds 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."

"During the extreme heat tests, the pouch surrounding Donut's battery lost its vacuum seal. This led researchers to explore whether the cell could still function under high-stress, high-temperature conditions, as damage has been known to cause fire in conventional lithium-ion batteries."

"Researchers conducted three tests: a baseline test of 5 cycles at 1C; a high-stress test of 50 cycles at 5C; and another final baseline test of 5 cycles at 1C to measure degradation. After the tests, the team observed a sharp drop in energy capacity, from 24.7 Amp-hours to 11.2 Ah."

Donut Lab conducted tests on its solid-state battery to assess its performance under damage. The battery showed a significant drop in energy capacity but did not catch fire, which is a notable success compared to conventional lithium-ion batteries. Previous tests indicated that damage could lead to thermal runaway in traditional batteries. Researchers performed multiple tests to evaluate the battery's resilience, ultimately confirming that it could withstand high-stress conditions without igniting.
