DOE Explains...Batteries | Department of Energy
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
How to store energy in your home
Home energy storage systems store generated electricity or heat, so that you can use the energy when you need it. Electricity can be stored in electrical batteries, or it can be converted into heat and stored in a heat battery. Heat can also be stored in heat batteries or in thermal storage, such as a hot water cylinder.
