Blowing up Batteries - for Science!
Scientists test rechargeable batteries to destruction
To understand how these batteries do fail, Dr. Paul Shearing, a senior lecturer in Chemical Engineering at University College London, and his colleagues, stress-tested batteries by massively overheating them, and observing the explosive outcome with thermal cameras and high-speed X-ray imaging to get a slow-motion 3-D picture of what happens when these batteries fail.
They hope understanding battery failure will help with the development of safety features that will make rechargeable batteries even more reliable. And as Dr. Shearing admits, watching stuff blow up is fun.
