Chinese 5 X 15 X 5mm Nickel-63 Nuclear Battery Has a 50-Year Lifespan
Chinese company Betavolt has announced an atomic energy battery for consumers with a touted 50-year lifespan. The Betavolt BV100 will be the first product to launch using the firm's new atomic battery technology, constructed using a nickel -63 isotope and diamond semiconductor material. Betavolt says that its nuclear battery will target aerospace, AI devices, medical, MEMS systems, intelligent sensors, small drones, and robots - and may eventually mean manufacturers can sell smartphones that never need charging.
Buying an electronics product that can go mains-free for 50 years would be amazing. However, the BV100, which is in the pilot stage ahead of mass production, doesn't offer a lot of power. This 15 x 15 x 5mm battery delivers 100 microwatts at 3 volts. It is mentioned that multiple BV100 batteries can be used together in series or parallel depending on device requirements. Betavolt also asserts that it has plans to launch a 1-watt version of its atomic battery in 2025.
[...] In its press release, Betavolt says its atomic battery is very different from similarly described power cells developed by the US and USSR in the 1960s. It says that the old nuclear batteries were large, dangerous, hot, and expensive products. [...] Meanwhile, the Betavolt BV100 is claimed to be safe for consumers and won't leak radiation even if subjected to gunshots or puncture.
The new, improved levels of safety stem from the choice of materials. Betavolt's battery uses a nickel -63 isotope as the energy source, which decays to a stable isotope of copper. This, plus the diamond semiconductor material, helps the BV100 operate stably in environments ranging from -60 to 120 degrees Celsius, according to the firm.
