Microporous polymer material for supercapacitors with large capacitance, high energy and power densities and excellent cycle life
Green Car Congress
AUGUST 22, 2011
Supercapacitors work on a different charge-storage principle than rechargeable batteries, and consist of electrochemical double layers on electrodes, which are wetted by an electrolyte. When a voltage is applied, ions of opposite charge collect on both electrodes to form wafer-thin zones of immobilized charge carriers. kW kg -1 respectively.
