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.
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.
The battery block that supplies current to these systems is usually sized according to the minimum required voltage of the external load and the ohmic voltage drop along the electrical line.

It is valuable to study the combined system of lead-acid batteries and super-capacitors in the context of photovoltaic and wind power systems [8–10]. Battery is one of the most cost-effective energy storage technologies. However, using battery as energy buffer is problematic .
The different contributions to the voltage drop in the lead–acid cell can be grouped in three main groups: those affecting the electrolyte resistance, those related to the material structure, electrodes and separators, and those involved in the electrochemical reactions at the double layer.
The result are as follows: The charging efficiency is higher when the super-capacitor is charged preferentially. Sequential charging is adopted, with stable current, small fluctuation and better battery protection performance. This study demonstrated the development and prospect of hybrid super-capacitor and lead-acid battery power storage system.
