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.
