Donut Lab solid-state battery retest by Finland’s VTT shows capacity rising to 110% at 80C, but weight data is still missing.

Donut Lab released the results of the second independent test showing that its solid-state battery can handle extreme heat without affecting its performance ...

VTT's second independent test shows Donut Lab's solid-state cell delivered 110% capacity at 80°C and survived 100°C discharge, but key claims remain unproven.

The Donut Lab solid-state battery was heated to the boiling point of water. Here’s what happened next.

Independent tests by VTT confirm Donut Lab’s solid-state EV battery can charge to 80% in 4.5 minutes without active cooling.

Independent high-temperature testing suggests the Donut Battery doesn’t just survive extreme heat, it improves efficiency — potentially rewriting the rulebook on EV battery safety and performance.

After securing another major partnership, Factorial is closing in on bringing its “groundbreaking” all-solid-state EV battery ...

Electric vehicles have advanced rapidly over the past decade, but battery technology remains the ...
