In this study, the electrochemical properties of activated carbon-coated lead anode for ultra batteries were investigated to high specific surface area. The coating solvent was distilled water and ethanol as solvent. The electrochemical characteristics were investigated by cycle stability tests. Lead anode with activated carbon for ultra-batteries improved cycle stability than that of pristine lead-acid batteries. When the activated carbon added to the coating solution was 8 g, the cycle performance was excellent compared to 12 g. It was found that the addition of activated carbon improves the cycle stability of the battery by suppressing the hydrogen generation reaction at the anode, but more than a certain amount of the activated carbon for coating the anode decreases the cycle stability.
