New Chinese Nuclear Phone Batteries Promise Endless Power Without Charging

Beijing-based startup Betavolt Technology is developing a groundbreaking nuclear battery for smartphones that could eliminate the need for charging. The Chinese company is exploring nuclear technology for various batteries, with claims that these batteries can retain a charge for an impressive 50 years. 


The technology functions similarly to batteries used in spacecraft and pacemakers, generating electricity through radioactive decay. Betavolt’s innovation incorporates a diamond semiconductor layer and a decaying nickel isotope, eliminating the use of plutonium, a highly radioactive metal. The company asserts that its nuclear battery does not emit radiation, ensuring safety and resilience in extreme temperature conditions. 


The compact module, named BV100, measuring just 15 x 15 x 5mm, can deliver a charge of up to 100 microwatts, suitable for modern smartphones. While the project is still in the early stages, Betavolt Technology aims to begin mass production. However, it may be a considerable amount of time before this technology becomes widely available for smartphones.
