Cell phones that die unexpectedly and electric vehicles that can’t make it to their destination highlight a common problem: battery limitations. Most rechargeable lithium-ion (Li-ion) batteries, found in everything from phones to cars, last only hours or days between charges. Over time, their performance declines, requiring more frequent charging.
To address this issue, researchers are exploring a new approach: nuclear batteries powered by radiocarbon. These small, affordable batteries could provide safe, long-lasting energy for decades without needing to be recharged.
