How does an electric car battery actually work? What happens inside a cell when it charges, why are there different chemistries, and what habits really affect its aging?

In this video, we'll follow the battery from the cell that stores energy to its repair, second life, or recycling. The goal is also to put into context the advice often repeated online: the 20-80% rule, 100% charging, fast charging, heat, preconditioning, and prolonged immobilization.
