A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential ...
Thermal energy storage
OverviewThermal BatteryCategoriesElectric thermal storageSolar energy storagePumped-heat electricity storageSee alsoExternal links
A thermal energy battery is a physical structure used for the purpose of storing and releasing thermal energy. Such a thermal battery (a.k.a. TBat) allows energy available at one time to be temporarily stored and then released at another time. The basic principles involved in a thermal battery occur at the atomic level of matter, with energy being added to or taken from either a solid mass or a liquid volume which causes the substance''s temperature to change. Some thermal batt…
