Lab Notes: Why you shouldn't leave your phone charging

Your phone battery doesn't like being fully charged or discharged. This is why it's sometimes advised that to extend its life, you shouldn't charge your phone beyond 80 per cent, or let it drop below 20 per cent. But what's actually happening inside a lithium-ion battery to cause this effect, and what does it mean for battery engineering — and the life of the battery in your phone, or your electric car? Jonathan Webb powers through the chemistry of batteries with Professor Neeraj Sharma.
