What is lead sulfuric acid battery? Basic analysis

    lead sulfuric acid battery are a common type of battery that is widely used in a variety of devices and vehicles. It is a device that converts chemical energy into electrical energy and has strong storage capacity and stability. Understanding the chemical equations of lead-sulfate batteries can help us better understand their working principles and maintenance methods. lead sulfuric acid battery is a device for storing and releasing chemical energy through REDOX reaction. In the discharge process, lead (Pb) on the negative electrode reacts with the negative active substance (usually lead dioxide, PB02) to form lead sulfate (pBS04), while releasing hydrogen ions (H+) and electrons (e-). On the positive electrode, lead dioxide reacts with sulfate ions (HSO4-) and hydrogen ions with electrons to form lead sulfate and water (H2O). In the whole process, the conversion between lead and lead dioxide and the transfer between sulfate ions and hydrogen ions together constitute the discharge reaction of the battery.

lead acid battery technology principle:

    in principle, when we need to charge, chemical reactions in the battery direction can change. During the charging process, the power supply provides electrical energy through an external circuit, which causes the reaction in the battery to move forward. The lead sulfate on the negative electrode will be reduced to lead and release hydrogen ions and electrons. The lead sulfate on the positive electrode is oxidized to lead dioxide and reacts with sulfate ions and hydrogen ions from an external power source to form lead sulfate and water. In this way, the battery stores electricity. In the discharge reaction and charge reaction, no additional substance is reduced or increased, because the two reaction conditions are the same, so it is a reversible reaction, but there are still many variables in the actual environment.

        the cathode reaction: Pb + HSO4 - Pbso4 + H + 2 e -

        is level reaction: Pbo2 + HSO4 - + 2 + 3 h e -   - > Pbso4 + 2 h2o

        overall reaction: Pb+Pb02+2HSO4+2H+ → 2ps04+2H2O

        the positive reaction: Pbso4 + 2 h2o - Pb02 + HSO4 - + 3 h + 2 e -

        the total response: 2 pbs04 + 2 h20 - > Pb + Pb02 HS04 - + 2 + 2 H +


    on the maintenance of it, for sulfuric acid lead battery maintenance, we can according to the chemical equation for guidance. First of all, we should always pay attention to the power of the battery to avoid excessive discharge, so as not to over-convert the lead in the negative electrode into lead sulfate. At the same time, we should also avoid overcharging, so as not to convert the positive lead sulfate into too much lead dioxide. In addition, regularly checking the electrolyte concentration of the battery to keep it in the appropriate range is also the key to maintaining the normal operation of the battery. By mastering the chemical equation of lead sulfuric acid battery, we can better understand its internal reaction mechanism, maintain and use the battery reasonably, extend its service life, and effectively use chemical energy to convert into electricity.

lead sulfuric acid battery advantages and characteristics of

    lead sulfuric acid battery has many advantages, such as the use of dilute sulphuric acid electrolyte, no flammability, high security stability; Reliable and stable performance, strong applicability; Can be used for floating charging, shallow charging and shallow discharge performance is excellent; High-capacity battery technology is mature and can be made into batteries with a capacity of thousands of ampere-hours, which provides convenience for large-scale energy storage. The wide operating temperature range and high operating voltage make it suitable for high rate discharge applications such as hybrid electric vehicles (HEV). However, it also has some disadvantages, such as more frequent daily maintenance, and lower energy and power density. Lead sulfate batteries, or lead-acid batteries, are a common type of battery. It is mainly composed of positive plate, negative plate, electrolyte and container. Among them, the positive plate is mainly lead dioxide, the negative plate is lead. In the charging state, the positive lead dioxide material dissociates into the unstable substance lead monoxide in the dilute sulfuric acid solution (electrolyte), the hydroxide ions are transferred to the electrolyte, and the lead ions remain on the positive plate. At the same time, the lead in the negative electrode is generated by an electrochemical reaction in the dilute sulfuric acid solution and transferred to the electrolyte, at which time there are two more electrons on the negative electrode. This potential difference between the positive and negative electrodes creates the electromotive force that enables the battery to supply power.

lead sulfuric acid battery market

    lead sulfate batteries are widely used in various areas, such as automobile, tractor, diesel engine starting and ignition, lighting, Power plant, substation, communication, hospital backup power supply, as well as a variety of battery cars, forklifts, forklifts, mining electric locomotive electric traction and lighting power supply. Please note that lead sulfate batteries may explode or burn under abusive conditions such as overcharge, short circuit, stamping, puncture, vibration, high temperature thermal shock, etc., so extra care is needed when using and handling them. In addition, when exporting, it is necessary to follow the relevant safety regulations and testing requirements, such as passing the UN 38.3 test, providing dangerous goods declaration documents, and affiying the corresponding dangerous goods label.

    With the rise of the new energy vehicle market and the promotion of infrastructure construction, the international market demand for lead sulfate batteries continues to grow. Especially in developing countries, due to the acceleration of infrastructure construction and industrialization, the demand for lead sulfate batteries is expected to grow further.
