Some batteries can be recharged and discharged repeatedly. People call these batteries batteries, or secondary batteries. Batteries do not store electricity directly, because electricity is the directional flow of electrons, and a large number of electrons cannot be stored in warehouses like ordinary objects. The reason why the battery can "store electricity" is that the external electric energy is used to promote the chemical reaction inside the battery and convert the electric energy into chemical energy for storage.[Advertising link removed - Mod]
