The design uses China's first diamond semiconductor material.
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 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 without charging for 50 years would be amazing. But 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. The company says multiple BV100 batteries can be used together in series or parallel depending on device requirements, and Betavolt has plans to launch a 1-watt version of its atomic battery in 2025.
The new BV100 is claimed to be a disruptive product on two counts. Firstly, a safe miniature atomic battery with 50 years of maintenance-free stamina is a breakthrough. Secondly, Betavolt claims it is the only company in the world with the technology to dope large-size diamond semiconductor materials, as used by the BV100. The company is using its 4th gen diamond semiconductor material here.
