Reduction of leakage current from supercapacitor by modifying electrode material

摘要

A composite material of an electrode unit includes: a porous electrode material being 50˜95 wt % of the composite material; an electret material being greater than 0 wt % and less than 15 wt % of the composite material; a dispersant material being 0˜15 wt % of the composite material; an adhesive material being 0˜15 wt % of the composite material; an electric conduction auxiliary agent being greater than 0 wt % and less than 30 wt % of the composite material. The porous electrode material includes porous particles and the electret material is distributed among the porous particles.
