    How Batteries Work: Energy Storage in Cells and Electric Vehicles

    Best quote from How Batteries Work: Energy Storage in Cells and Electric Vehicles

    “

    We don’t actually store electricity at all. Instead, we perform a sort of alchemical trick where we force that kinetic energy to transform into a quiet, resting state called chemical potential energy.

    ”

    This audio lesson was created by a BeFreed community member

    Input question

    How does a battery work and if you can explain how a battery works then how does a large cell or a large battery like an electric vehicle? How is electricity able to be stored and then used later it doesn’t make any sense to me.
