Abstract
Supercapacitor modification of utility in electric vehicle powering, and directed to optimizing specific capacitance and rate capability by promoting ionic motions in electrolyte during charging and discharging, by means of a high coercivity faces-poled sheet or plate magnet comprising a magnetized metal backing part adjacent the back of a composite porous supercapacitor electrode, ie., at the side away from the region of bulk electrolyte access to pores. A portion of casing of this magnetically enhanced supercapacitor may integrate the plate magnet or the latter may be a separate component applied or fitted to the casing, removably, if desired, to facilitate possible re-magnetization. Except for the magnetized metal backing part and addition of a paramagnetic substance to the electrolyte, all the essential components are known in supercapacitors.
