The distribution of internal resistance in a 5-cell electrochemical capacitor comprising an electrode material with 80wt.% RuO 2 .xH 2 O and 20wt.% activated carbon and an electrolyte of 38wt.% H 2 SO 4 acid solution was analyzed. It was found that over 94% of the internal resistance in the capacitor was contributed to various contacts with the current collector of...
