A hybrid lead-carbon battery based on high surface area carbon as the anode and lead dioxide as the cathode is investigated using a sulfuric acid solution as the electrolyte. The behaviors of the anode and cathode during charging and discharging are studied by using the Hg/Hg2SO4 reference electrode. The unit cell performance is confirmed in the discharge mode and a short-term cycle test. The capacities of the cell were 76.1, 60.3, 40.5, and 31.7 mAh at discharge currents of 150, 300, 600, and 900 mA, respectively. In the short-term cycle test, the capacity of the cell, 52.3 mAh at the first cycle, continuously increased to 66.7 mAh upon the fifth cycle (cut-off voltage 0.5 V in the deep cycle mode), indicating high feasibility of the hybrid lead-carbon battery as a large-capacity energy storage system. |
