A Chinese start-up has developed a coin-sized nuclear battery which they claim can generate electricity for 50 years without needing to be charged.
While still in its development stage, Betavolt says the miniature battery can be used by everyday people.
The 15x15x5mm battery uses atomic energy and has the potential to power a smartphone in the future.
Chinese startup Betavolt presented a compact, safe and durable nuclear battery BB100 with the Nickel-63 isotope and diamond semiconductors.

The battery emits energy by utilising a decaying radioactive isotope of nickel.
Between the layers of nickel are sheets of a single crystal diamond semi-conductor that are just 10 microns thick.
The company says it can store 3300 megawatt hours, holding the energy density 10 times more than a conventional lithium battery.
“I really always believed that whoever invents the battery that lasts forever is going to rule the world.”
