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.
For an improvement to a supercapacitor of known construction comprising a casing and within the casing an electrolyte, a porous composite electrode composed of first and second materials where the first procures electrical double-layer capacitance and the second procures pseudo-capacitance, a counter electrode, and terminals in connection respectively with said porous composite electrode and said counter electrode, an improvement characterized in that
The improvement as in any single preceding claim, wherein an indifferent paramagnetic substance is present in said electrolyte.
