Donut Lab’s all-solid-state battery delivers 400 Wh/kg of energy density, enabling longer range, lighter structures, and unprecedented flexibility in vehicle and product design. It can be charged to full in just five minutes without limiting charging to 80%, and supports full discharge safely, repeatedly, and reliably.
And:
Unlike conventional lithium-ion batteries, the Donut Battery experiences minimal capacity fade over its lifetime, with a design life of up to 100,000 cycles, offering practical longevity that far exceeds existing technologies. Safety is built in at the core: no flammable liquid electrolytes, no thermal runaway chains, and no metallic dendrites. This eliminates the root causes of battery fires, making the Donut Battery extremely safe and truly revolutionary.
And:
Performance has been rigorously tested across extreme conditions. At –30°C, the battery retains over 99% of its capacity, and when heated to temperatures exceeding 100°C, it continues to retain over 99% capacity with no signs of ignition or degradation.
The Donut Lab solid state battery is made entirely from abundant, affordable, and geopolitically safe materials, does not rely on rare or sensitive elements, and demonstrates a lower cost than lithium-ion.
I had to quote all of that because it sounds incredible; it addresses battery issues found in the current leading EVs. I truly want to believe: we need better, affordable, and abundant batteries. Yet, we will have to wait and see.
