摘要：

The lead-acid batteries are the most often used in human life, because of their low cost, good reversibility and high potential but they have limit cycle ability with low capacitance. The main causes of this problem are forming recrystallization of PbSO4 on electrodes surface during cycles which the recrystallization of PbSO4 is known as sulfation. In this study, formation process of sulfation was investigated depending on charge and discharge cycle numbers. And we decomposed sulfation to renew cycle ability of lead-acid batteries. The renewed lead-acid batteries recovered to 84% compared to first capacity after 600 cycles.
