- Donut Lab launched its solid‑state EV battery at CES, calling it the world’s first ready for OEM vehicle manufacturing.
- VTT Technical Research Centre of Finland performed an independent assessment, with video results released starting Feb 23, 2024.
- Donut Lab’s battery claims a five‑minute full charge, 400 Wh/kg energy density, and up to 100,000 cycles with minimal capacity fade.
- The battery retains over 99 % capacity at –30 °C and >100 °C and avoids dendrite‑related fires, according to Donut Lab’s testing.
- Verge Motorcycles will equip its TS Pro and Ultra models with the battery, promising 217 mi range (up to 370 mi with extended pack) and 186 mi in ten minutes of charging.
- Donut Lab says the battery uses abundant, affordable, geopolitically safe materials and costs less than lithium‑ion batteries.
Why it matters: The validation gives automakers a proven alternative to lithium‑ion cells, offering faster charging, higher energy density, longer life and lower material costs, which could accelerate EV rollout and give early adopters like Verge a market edge.
