PROBLEM TO BE SOLVED: To provide a capacitor electrode for a lead storage battery, which is superior in strength, small in resistance and further, large in capacity.SOLUTION: A capacitor electrode for a lead storage battery comprises: a capacitor layer including a capacitor electrode active material, a conductive material and a binding agent; and a support material glued to the capacitor layer directly or indirectly. The support material has an air permeability under 10 sec, and a surface roughness (Ra) of 0.5-50 μm.SELECTED DRAWING: None |
