These batteries are made from nuclear waste and could last thousands of years.🔋
Radioactive diamond batteries were first developed by a team of physicists and chemists from the Cabot Institute for the Environment of the University of Bristol. The invention was presented as a betavoltaic device, which means that it’s powered by the beta decay of nuclear waste.
A typical betavoltaic cell consists of thin layers of radioactive material placed between semiconductors. As the nuclear material decays, it emits beta particles that knock electrons loose in the semiconductor, creating an electric current. Nano-diamond batteries from NDB are described as alpha, beta, and neutron voltaic batteries and have several new features according to their website.The firm calculates that the batteries could last up to 28,000 years, which means that they could reliably power space vehicles in long-duration missions, space stations, and satellites. Drones, electric cars, and aircraft on Earth would never need to make stops to be recharged.
However, the diamond betavoltaics developed by Arkenlight won't go that far. The company is working on designs that stack up lots of their carbon-14 betabatteries into cells. To provide high power discharge, each cell could be accompanied by a small supercapacitor, which could offer an excellent quick-discharge capability.
