Betavolt, a Chinese startup, reveals a mini nuclear battery with a 50-year lifespan and no recharging needed. The compact atomic energy device, smaller than a coin, integrates 63 nuclear isotopes for efficient power generation. After successful pilot testing, the mini nuclear battery is set for mass production, targeting diverse applications like aerospace, AI equipment, medical devices, microprocessors, drones, and micro-robots. The mini nuclear battery operates by converting energy from decayi
