Normally, as the lead–acid batteries discharge, lead sulfate crystals are formed on the plates. Then during charging, a reversed electrochemical reaction takes place to decompose lead sulfate back to lead on the negative electrode and lead oxide on the positive electrode.
The end of life is usually considered when the battery capacity drops to 80% of the initial value. For most lead–acid batteries, the capacity drops to 80% between 300 and 500 cycles. Lead–acid battery cycle life is a complex function of battery depth of discharge, temperature, average state of charge, cycle frequency, charging methods, and time.
The research on lead-acid battery activation technology is a key link in the “ reduction and resource utilization “ of lead-acid batteries. Charge and discharge technology is indispensable in the activation of lead-acid batteries, and there are serious consistency problems in decommissioned lead-acid batteries.
A lead acid battery consists of a negative electrode made of spongy or porous lead. The lead is porous to facilitate the formation and dissolution of lead. The positive electrode consists of lead oxide. Both electrodes are immersed in a electrolytic solution of sulfuric acid and water.
The discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.
Charging and discharging a battery with poor consistency will hardly allow the battery to be effectively activated. According to the characteristics of lead-acid batteries, we carry out research on lead-acid battery activation technology, focusing on the series activation technology of lead-acid batteries with poor consistency.
