Wuxi US SORENSEN Battery Battery SAL12-200 complete model definition? Battery is a battery. The role is limited battery power can be stored for use in the right place. Battery works by chemical energy into electrical energy. Fill it with spongy lead negative stereotype as fill for the positive stereotype of lead dioxide, with 22 to 28% * for dilute electrolyte. During charging, the electrical energy into chemical energy, and chemical energy discharge into electricity. The battery during discharge, the metal lead is a negative electrode, an oxidation reaction, is oxidized to * lead; lead dioxide is the positive electrode, reduction reaction occurs, is reduced to * lead. When using a DC battery charging poles were generated lead and lead dioxide. After power is removed, it returns to the state before the discharge, chemical composition of the battery. Lead-acid batteries that can be recharged and discharged batteries, called secondary battery. Its voltage is 2V, usually three lead-acid battery used in series, the voltage is 6V. On the use of the car is 6 12V lead-acid battery in series into the battery pack. Lead-acid batteries in use for some time to add to * keep the electrolyte contains 22 to 28% diluted *. When the discharge electrode reaction is: PbO2 + 4H ++ SO42- + 2e- = PbSO4 + 2H2O negative reaction: Pb + SO42--2e- = PbSO4 overall reaction: PbO2 + Pb + 2H2SO4 === 2PbSO4 + 2H2O (right The reaction is discharged, left reaction is charging)
