The electrode is mainly made of lead and its oxides, and the electrolyte is a type of battery in sulfuric acid solution. English name: Lead acid battery. In the discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; In the charging state, the main component of the positive and negative electrodes is lead sulfate. It is divided into exhaust type batteries and maintenance free lead-acid batteries. The battery mainly consists of a tubular positive electrode plate, negative electrode plate, electrolyte, separator, battery slot, battery cover, pole, and liquid injection cover. The electrodes of an exhaust battery are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid
