The working principle of lead-acid batteries is based on the chemical reaction of lead and lead oxide in sulfuric acid electrolyte. During the charging process, lead and lead oxide are respectively converted into lead sulfate, while releasing electrical energy. During the discharge process, lead sulfate is converted into lead and lead oxide, thereby consuming electrical energy. This process is reversible, so lead-acid batteries can be repeatedly charged and discharged, thereby achieving energy storage and release.

Lead acid batteries, an energy storage device widely used in various application scenarios, have been widely recognized by global users due to their reliable, stable, and cost-effective characteristics. Lead acid batteries play a crucial role in automotive starting systems, backup power sources, and even large-scale power systems.

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.

Lead acid batteries are a type of energy storage equipment that has undergone long-term development and widespread application, known for their stability and reliability. Since its invention, lead-acid batteries have played an important role in many fields, such as automotive starting, uninterruptible power supply systems (UPS), electric tools, and renewable energy systems.
