Lead acid batteries are a mature and reliable energy storage device. Despite facing some technical challenges, their excellent performance and wide range of application scenarios still make them occupy a place in the field of energy storage. Whether it's starting a car, serving as a backup power source for power supply, or for various other applications, lead-acid batteries can provide stable and reliable power support. In the future, with the continuous progress of technology, we have reason to believe that lead-acid batteries will be applied in more fields to better meet the energy needs of society.

The working principle of lead-acid batteries is relatively simple, mainly relying on the chemical reaction between lead and lead oxide (usually referred to as lead-acid) to store and release electrical energy. During charging, lead sulfate is oxidized to lead dioxide at the positive electrode and reduced to lead at the negative electrode; When discharging, this process proceeds in the opposite direction, releasing electrical energy.
