This safe nuclear battery could last decades on a single charge

Researchers are always developing better battery technologies, hoping to find ones that last a long time and never need to be recharged—and this month, we have yet another exciting breakthrough.

South Korean scientists from the Daegu Gyeongbuk Institute of Science & Technology recently presented a prototype battery that works according to the betavoltaic principle. As the researchers explain:

“Nuclear batteries generate power by harnessing high-energy particles emitted by radioactive materials.
