Donut Lab's Solid-State Battery Survives Brutal Nail Test, Backed by Intertek

Donut Lab has announced that its solid-state battery cell has successfully passed a nail penetration test conducted by Intertek, a globally recognized testing and certification organization. The test is designed to simulate severe internal short circuits and is considered a crucial indicator of battery safety.

The company emphasises that the cell did not ignite or explode during the test, highlighting the potential of its solid-state technology to offer higher safety levels compared to conventional lithium-ion batteries. This milestone brings Donut Lab one step closer to commercialising its battery for use in electric vehicles and other high-demand applications.

While full technical details and timelines have not been disclosed, the successful completion of a third-party nail test provides independent validation of the cell’s resilience. The outcome is likely to attract interest from automakers and investors looking for safer, next-generation battery solutions.
