We subjected these batteries to the nail penetration test, a common method for assessing lithium-ion battery safety. Driving a stainless steel nail through a charged battery simulates an internal short circuit; if the battery catches fire, it fails the test. When we drove a nail through our charged batteries, they withstood the impact without ...
