Li-ion roars can predict early battery failure, MIT boffins say

Batteries emit distinct acoustic signatures depending on how they’re failing – a bit like people, really
When lithium-ion batteries degrade, they emit acoustic signals that reveal what’s going wrong inside. Now, MIT researchers say they’ve figured out how to interpret those sounds, and the subtle creaks and pops that come before major failures, to help predict problems before things go up in smoke.…The RegisterRead More
