China has begun mass production of nuclear batteries and they’re smaller than a coin.

They need no charging, no sunlight, no wires, and no maintenance.

Just pure, continuous energy for up to five decades.

Built by Betavolt, this battery converts nuclear decay into electricity. It’s completely sealed, emits zero external radiation, and is safe for daily environments.

The current version produces 100 microwatts, enough for sensors, medical implants, or trackers.

But a 1-watt version is already in development, capable of powering drones, industrial systems, and even smartphones.
