Solid state battery development
Donut lab solid state, updates will follow below:
15 jan 2026 -
High Energy Density – Claimed ~400 Wh/kg, higher than most current lithium‑ion cells.
Ultra‑fast Charging – Capable of a full charge in ~5 minutes without slowing at 80 %.
Extended Cycle Life – Up to ~100,000 full charge/discharge cycles with minimal capacity loss.
Extreme Temperature Tolerance – Retains over 99 % capacity from around −30 °C to above 100 °C.
Intrinsic Safety – All-solid-state design with no flammable liquid electrolyte, reducing fire risk and thermal runaway.
Abundant & Non-Strategic Materials – Uses materials that are low-cost, abundant, and not reliant on lithium or rare earth elements.
Lower Cost Potential – Simplified architecture and materials could make overall system cost lower than conventional lithium-ion batteries.
Flexible Integration – Versatile form factors for custom sizes, voltages, shapes, and even structural integration.
