Electrochemical energy conversion

Electrochemical energy conversion is a field of energy technology built around electrochemical methods of converting energy, including fuel cells and photoelectrochemical devices, as well as electrical storage devices such as batteries and supercapacitors. It has become increasingly important for automotive propulsion, as advances in the field have produced more powerful, longer running batteries that extend how long electric vehicles can operate.
