0 years of history, due to low prices, the battery is still the largest output of the battery. The main components of lead-acid batteries are positive and negative plates, electrolyte, separator, battery tank, in addition, there are some parts such as terminals, connecting strips, exhaust bolt and so on. Using lead dioxide anode active material, lead as anode active material, sulfuric acid as electrolyte, microporous rubber, sintered polyvinyl chloride, glass fiber, polypropylene for partitions. Lead acid battery can be divided into different types according to the scope of use, the shape and structure, the structure of the plate, the maintenance of the electrolyte and the charge. Use is divided to start type, fixed type, traction, railway car, vehicle engine, marine, aviation, torpedo, with tanks, for miner's lamp, AIDS to navigation; according to the plate structure can be divided into paste type, tube type and formation; according to the state of charge can be divided into dry discharge state, state of charge, wet charged state and liquid state of charge, maintenance free and low maintenance battery; according to the battery cover and the exhaust bolt structure divided into open type, type exhaust valve controlled sealed, acid flameproof type and acid hydrogen elimination type. Lead-acid battery main advantage is relatively cheap, in the world within the scope of production can be low rate and high rate discharge of the battery, the price is cadmium nickel battery 1 / 6 to 1 / 5; 2 high rate discharge performance and high and low temperature performance is good, + 60 DEG C under the condition of in - 40 DEG; third, the battery voltage in practical battery is highest, up to 2.2V. Fourthly, no memory effect; the electric energy efficiency as high as 60%. But it is lower than the energy, the service life is shorter than the cadmium nickel and the nickel iron battery, make the small size is quite difficult, but the cadmium nickel alkaline button type battery can be made smaller than the H 0.5A size. In addition, as the main raw material of lead acid battery is lead, antimony and sulfuric acid, the precipitation of antimony hydride and other compounds can cause environmental hazards.
