This tiny radioactive battery can last 50 years without recharging — and it's coming in 2025

BetaVolt's BV100 is smaller than a coin and contains a radioactive isotope of nickel that decays into copper and supplies power to a device for up to 50 years. But it probably won't power your smartphone anytime soon, an expert suggests.

Interesting! Ideally, the necessity of shielding would be minimal, if all of the emitted radiation would be used as an energy source. So, by increasing the efficiency, one would reduce the need for shielding. You'd still need to take into account accidental damage, of course.

I think technology like this definitely has potential!

The article title says "50 years without recharging" but this is misleading as that power source isn't rechargeable.
Having said that, it's a great little piece of engineering.
