Electrochemical energy conversion is a field of energy technology concerned with Electrochemical methods of energy conversion including fuel cells and photoelectrochemical. This field of technology also includes electrical storage devices like batteries and supercapacitors . It is increasingly important in context of automotive propulsion systems.^[2] There has been the creation of more powerful, longer running batteries allowing longer run times for electric vehicles.^[3] These systems would include the energy conversion fuel cells and photoelectrochemical mentioned above.
