Beijing Betavolt New Energy Technology has developed the BV100, a coin-sized nuclear battery that can operate for up to 50 years without recharging. While it produces low power output, approximately 100 microwatts at 3 volts, it is intended for medical equipment and aerospace technology, with mass production already underway.

The battery utilizes Nickel-63, which decays into copper, releasing beta particles converted into electricity via diamond semiconductor technology. The BV100 offers significant advantages over conventional lithium batteries, including a 100-fold energy storage capacity, operation in extreme temperatures from -60°C to 120°C, and no risk of fire or explosion.

Future plans include a more powerful 1-watt version. The technology has potential applications in space missions, medical devices, and long-duration drones, generating global interest in nuclear battery technology.
