The composition and operating principle of lead-acid batteries. Lead acid batteries are composed of positive electrode plate, negative electrode plate, separator, electrolyte, plastic tank, etc. The positive active material of lead-acid batteries is lead dioxide (PbO2), the negative active material is lead (Pb), the electrolyte is dilute sulfuric acid, and the positive and negative electrodes are separated by a separator. Ions in the electrolyte can pass through the micropores in the separator, while electrons on the electrode cannot pass through the separator. After the discharge of lead-acid batteries, the active material lead dioxide (PbO2) on the positive electrode plate is converted into lead sulfate (PbSO4) and adheres to the positive electrode plate, while the active material lead (Pb) on the negative electrode is also converted into lead sulfate (PbSO4) and adheres to the negative electrode. The sulfuric acid in the electrolyte disperses into the electrode plate, causing a decrease in the concentration of the electrolyte. Lead acid batteries undergo the opposite reaction during charging. After charging and discharging reactions, lead-acid batteries can be reused until the stored capacity does not meet the requirements of the electrical appliance, and the lifespan is terminated. Analysis of the Global Lead Acid Battery Market Size: In the past decade, with the development of the international energy economy and the increasing improvement of people's living standards, the application areas of lead acid batteries have been continuously expanding, and the market demand has also increased significantly. Lead acid batteries have accounted for more than 85% of the market share in secondary power sources.
