A Chinese startup called Betavolt has developed a nuclear-powered battery smaller the size of a coin, which can power smartphones for 50 years without the need to recharge.
Its technology behind the world’s first miniaturised atomic energy system involves converting the energy released by decaying the nickel-63 nuclear isotopes into electricity.
Betavolt has already initiated pilot testing and is planning to mass-produce the battery for commercial applications, including for smartphones and drones.
Technological Vision
Media reports cited a press release by the company, in which it said that its new atomic energy batteries “can meet the needs of long-lasting power supply in multiple scenarios, such as aerospace, AI equipment, medical equipment, microprocessors, advanced sensors, small drones, and micro-robots.” The startup believes that the innovation will give China a competitive advantage in the era of AI.
Next year, Betavolt plans to produce a battery with 1 watt of power. The battery’s small size allows for multiple units to be connected, which increases the power output.
The Chinese startup envisions a future where mobile phones and drones never need to be recharged. Eventually, the battery could also be used to power medical devices such as pacemakers and artificial hearts.
Radiation Risks and Safety
The battery is also designed to be safe. Betavolt insists that carrying the capsule of radioactive decay is “absolutely safe,” as there is no external radiation.
According to the company, the battery’s layered structure prevents it from catching fire or exploding when subjected to sudden force, such as gunshots or puncture. Moreover, it can operate in the wide temperature range of -60 degrees Celsius to 120 degrees Celsius.
