Analysis of the characteristics of lead-acid batteries

The lead-acid battery (VRLA), and the electrode is mainly composed of lead and its oxide, the electrolyte is a battery of the sulfuric acid solution.

Lead-acid battery charged state, the positive main ingredients for lead dioxide, negative main ingredients to lead; Discharge state, the main components are all lead sulfate is negative.

French plante invention lead-acid batteries in 1859, has experienced nearly 150 years development course, lead-acid battery in terms of theoretical research, the species and varieties of products, product electrical performance, etc got great progress, both in transportation, communications, electric power, military and in the field of navigation,special economies, lead-acid batteries have played an indispensable role.

Lead-acid battery application when the longest history, the most mature technology and low cost of the battery, the implemented large-scale commercial applications. But it is lower than energy, high self-discharge rate, discharge voltage and performance degradation), cycle life is low, the weight of lead, and lead as may be produced in the process of production and recovery of heavy metals pollution of the environment.
