With the auto industry continues to expand, more and more people know the car battery. So what is the car battery, and how many kinds of car battery are there in the world? If you are interested in this, please read this article below.

Most car batteries are lead-acid batteries. Simply, it is a electrochemical device which can turn chemical energy into electrical energy. Lead-acid battery from the positive and negative plates, separators, casing, electrolyte and wiring trailer coupling etc., the discharge of chemical reaction is to rely on the positive plate active material (lead dioxide PbO2) and the negative plate active material(sponge-like pure lead Pb ) in the electrolyte (sulfuric acid H2SO composition and water H2O) under the effect. A standard 12V lead-acid battery contains six modules,each generate about 2V power supply (per power supply has positive and negative column: column inscribed with the positive ”+” sign, dark brown; negative polemoment a “-” sign, light gray).

Traditional car batteries will occur in the course of the electrolyte is declining, it is becausethe gate electrode holder, the traditional lead-antimony alloy car battery, antimony will pollute the negative plate cavernous pure lead, weakened after the car battery is fully charged within back-EMF, cause excessive decomposition of water, a large number ofoxygen and hydrogen escape from the positive and negative plate, so that the electrolyte reduction.
