AI overview
A rechargeable battery is a device that stores electrical energy and can be used repeatedly by being charged, discharged to power something, and then charged again many times. This matters because rechargeable batteries can be reused instead of being thrown away after one use, making them more practical and economical for powering everyday devices.

A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator) is a type of electric battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. It is composed of one or more electrochemical cells. The term "accumulator" is used as it accumulates and stores energy through a reversible electrochemical reaction. Rechargeable batteries are produced in many different shapes and sizes, ranging from button cells to megawatt systems connected to stabilize an electrical distribution network. Several different combinations of electrode materials and electrolytes are used, including lead–acid, zinc–air, nickel–cadmium (NiCd), nickel–metal hydride (NiMH), lithium-ion (Li-ion), lithium iron phosphate (LiFePO4), and lithium-ion polymer (Li-ion polymer).
