"Chinese-developed nuclear battery has a 50-year lifespan -- Betavolt BV100 built with Nickel-63 isotope and diamond semiconductor material."
"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."
"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."
Wow, I didn't even know diamond semiconductors were a thing.
"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. For example, some old-tech atomic batteries used Plutonium as the radioactive power source. Meanwhile, the Betavolt BV100 is claimed to be safe for consumers and won't leak radiation even if subjected to gunshots or puncture."
