Battery

Battery [3] is a kind of cell, its role is to be able to store a limited power, FRU 92P1137 in appropriate places for use. How does it work is to chemical energy into electrical energy.

It is filled with spongy lead of lead as cathode, filled with lead dioxide as positive electrode of lead and 1.28% of the sulfuric acid used as electrolyte. While charging, electrical energy into chemical energy, discharge chemical energy into electrical energy again. Battery discharge, the metal lead is the cathode oxidation reaction, was oxidized to lead sulfate; dioxide lead is cathode, reduction reaction occurs, is reduced to lead sulfate. When using DC battery charging, the bipolar lead and lead dioxide were generated. After the removal of power, it recovered to pre-discharge state, the composition of chemical batteries. Lead-acid battery is able to repeatedly charge and discharge the battery, called the secondary battery. Its voltage is 2V, usually three lead-acid batteries in series up to use, voltage is 6V. Vehicle using a six lead-acid batteries in series into a 12V battery packs. Lead-acid batteries in use for some time to add distilled water to maintain electrolyte containing 22 ~ 28% of diluted sulfuric acid. 02K6651

Discharge, the electrode reaction: PbO2 + 4H + + SO42-+ 2e-= PbSO4 + 2H2O

Negative reaction: Pb + SO42-- 2e-= PbSO4

The overall reaction: PbO2 + Pb + 2H2SO4 === 2PbSO4 + 2H2O (the right response is discharge, to the left reaction is charging)

Battery Application

[1] [2] lead-acid batteries are the following types of products, its use as follows:

Start-type batteries: mainly used in automobiles, motorcycles, tractors, diesel engines and other start-up and lighting;

Fixed-type batteries: mainly for communications, power plants, computer systems as a protection, automatic backup power source;

Traction-type batteries: Mainly used for a variety of battery vehicles, forklift trucks, forklifts and other power supply;

Railway Battery: mainly used in railway locomotives, electric locomotives, passenger cars starting, lighting power;

Energy Storage Battery: mainly used for wind, 02K6928 solar and other energy consumption can be stored;

Batteries - the main ingredient

Lead-acid batteries constitute the main ingredients are as follows: anode plate (lead peroxide. PbO2 )---> active substances cathode plate (sponge-like lead. Pb) ---> active substance electrolyte (sulfuric acid) --- "Sulfuric acid ( H2SO4) + water (H2O) battery shell isolation plates other (liquid port plug. cover, etc.)02K6620
