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 bat
