Supercapacitors: A Brief Overview - Mitre Corporation
www.mitre.orgthe maximum power P. max. for a capacitor [1-2, 5] is given by: ESR V P × = 4. 2 max. (4) This relationship shows how the ESR can limit the maximum power of a capacitor. Conventional capacitors have relatively high power densities, but relatively low energy densities when compared to electrochemical batteries and to fuel cells. That is, a
