Batteries (or accumulators) are electrochemical energy storage devices used for a wide variety of purposes. Compared to other storage devices batteries have very high energy densities, but low power density and therefore high charging times. Some modern high performance batteries do however reach power densities that are promising for braking energy storage in automotive and (to a smaller extent) railway applications.
