Description
Summary:An unusual charge transfer domain for electrochemical processes is investigated. Criteria are described which facilitate an ultrahigh specific power domain. This domain is defined for faradaic processes that are long when compared to the electrochemical double layer charging time, as a specific power over 10000 W/kg occurring at a specific energy over 1 Wh/kg. Traditionally compared to capacitors, faradaic processes can achieve high specific energy, >1 Wh/kg, but limited specific power,
