Chinese company Betavolt recently unveiled its BV100 battery which is smaller than a coin in size but has a lifespan of around 50 years and doesn’t require recharging.
Atomic batteries aren’t new. Both the United States and the USSR produced such power units during the 1960s, but these nuclear batteries were large, dangerous, and expensive to make. Plutonium was used as the radioactive power source for the first atomic batteries, but science has come a long way since, and Betavolt’s revolutionary battery now relies on a much safer isotope, nickel-63, which decays to a stable isotope of copper. The diamond semiconductor material in the battery allows it to run stably in environments ranging from -60 to 120 degrees Celsius. Measuring just 15mm x 15mm x 5mm, the new Betavolt BV100 constantly generates electricity as the isotopes degrade, unlike conventional batteries which simply store energy.
