@chillcapi: Your battery doesn't store electricity. So what's in there? A lithium-ion battery is two sheets, graphite and a metal oxide, split by a plastic film thinner than a hair. Charged, lithium is packed into the graphite. When you use your phone, the lithium ions slip through the film, but their electrons can't, so they race around through your phone. That's your power. Charging just shoves the lithium back. So a battery stores lithium in the wrong place. And if that film tears, electrons take a shortcut and the cell can catch fire. Never use a swollen or punctured battery. What % is your phone at right now? #battery #lithiumion #howitworks #Science #physics
