In the discharge state of lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main components of the positive and negative electrodes are both lead sulfate. With the demand for high-power use of high-power lead-acid batteries, the demand for high-power lead-acid batteries is increasing, and high-power lead-acid batteries usually refer to backup power sources with short emergency power time and large discharge current. High-power lead-acid batteries have the characteristics of high output power, small footprint, low battery cost and energy consumption.
