194 - Playing with batteries with Xinyan Huang

Professor Xinyan Huang from Hong Kong Polytechnic University shares his expertise on battery fires and the various experimental methods researchers use to trigger thermal runaway events under controlled conditions. • Terminology matters - "thermal runaway" more accurately describes battery failure than "ignition" as the critical reactions occur inside the cell • Nail penetration testing is widely used but contains surprising complexities, including nail material, penetration depth, velocity ...
