Abstract
A current collector for use in an electric double layer electrochemical capacitor having a sulfuric acid electrolyte. The current collector uses a conducting carbon (e.g., graphite foil) basis with p-type conductivity. A protective film covers at least a portion of the graphite foil basis. The protective film is comprised of a conducting composite material made with a conducting carbon and a conducting organic polymer with p-type conductivity. The protective film is grown on the current collector basis such that it preferably fills the pores of the current collector basis. A lug portion of the current collector basis may be protected with an insulating polymer material.
