Abstract
A primary electrochemical cell having an oxidizable active anode material, a cathode current colletor including a layer of a catalyst material for reducing the liquid cathode material, and an electrolytic solution comprising a liquid cathode material and an electrolyte solute dissolved therein. The catalyst material comprises a carbon black having a surface area of 250 square meters per gram or greater and a dibutyl phthalate absorption number of 125 cubic centimeters per 100 grams of carbon black or greater.
