The battery has the advantages of stable voltage, reliable power supply, convenient movement, etc., which is widely used in power plants, substations, communication systems, electric vehicles, aerospace and other departments. The battery mainly has a common lead-acid battery, a basic cadmium-nickel battery, and a valve-controlled sealed lead-acid battery. The ordinary lead-acid battery has problems with short service life, low efficiency, complicating environment, and the acid fog contamination environment, which has been widely used, and has gradually been eliminated by the valve-controlled lead-acid battery. Valve-controlled sealing lead-acid storage batteries use sealing structures, there is no phenomenon of general lead-acid battery, and electrolyte leakage, etc. Alikewind-free battery. It has been widely applied to many fields such as post and telecommunications, ship traffic, emergency lighting. The basic cadmium-nickel-nickel battery is small, the discharge magnification is high, the operation and maintenance is simple, long life, but due to its monomer voltage, easy leakage, high cost, and easy to cause contamination, it is limited, currently Applied on power tools and various portable electronic devices. The ordinary lead-acid battery is mainly composed of a polar plate, an electrolyte, and a battery cell. The positive and negative plates are constructed from the grid and the active material, wherein the active material on the positive electrode plate is brown, the active substance on the negative electrode plate is dark gray sponge pure lead (Pb). The electrolytic solution is made of distilled water (H2O) and pure sulfuric acid (H2SO4) at a certain ratio. During the charging process, the electrolyte is chemically reacted in the active substance on the positive and negative electrode plate, thereby turning the electrical energy into chemical energy; during discharge, the electrolyte is also chemically reacted with the active material on the positive and negative plate. , Put the chemical energy converted into the battery to supply the load. In order to make the chemical reaction can be carried out normally, the electrolyte must have a certain concentration. The battery cell is a polar plate group and an electrolyte container, which must have better acid resistance, insulation and higher mechanical strength.
In the battery positive and negative electrode plate, the discharge process of the battery is started. At this time, the positive electrode plate potential decreases, the anode plate potential rises, the active material (PbO2 and Pb) on the positive and negative plates (PbO2 and Pb) are constantly converted to the lead (PBSO4), and the sulfuric acid in the electrolyte is gradually converted to water, and the specific gravity of the electrolyte Gradually decline, thereby increasing the internal resistance of the battery and the electromotive force is lowered. If the output voltage is connected to the output voltage than the DC power supply of the battery-side voltage between the battery, the battery is started. At this time, the positive electrode plate potential rises due to the positive charge aggregation, and the negative electrode plate potential decreases due to negative charge aggregation, and the PBSO4 on the positive electrode plate gradually becomes PbO2, and the PBSO 4 on the negative electrode plate gradually changes into a sponge PB. At the same time, the synthesis of H2SO4 in the electrolyte is gradually increased, and the water molecules are gradually decreasing, and the specific gravity of the electrolyte is gradually increased, and the battery end voltage is also increasing.
