Lead-acid batteries

source:Industry News release time:2023-02-03 Hits: Popular:AG11 battery

　　 Lithium Battery GN6020

　　The French invented the lead -acid battery in 1859, and has gone through the development process of nearly 157 years. In terms of theoretical research, lead -acid batteries have made great progress in terms of product types and varieties, product electrical performance, etc., regardless of whether Whether it is traffic, communication, electricity, military, or in various economic fields of navigation, and aviation, lead -acid batteries have played an indispensable and important role. It is also a mature electric vehicle battery.

　　Lead -acid battery composition: Positive and negative electrodes are lead and lead, respectively, and electrolytes are sulfate.

　　Lead -acid batteries can be divided into two categories:

　　Water injection type lead -acid battery:

　　Water injection type lead -acid batteries are cheap, but they need to be maintained frequently to supplement the electrolyte.

　　Valve -controlled lead -acid battery:

　　Valve -controlled lead -acid batteries automatically control the excess gas generated by the internal charging or abnormal work of the sealing battery through the safety control valve, exempting maintenance, and more in line with the requirements of electric vehicles.

　　Generally speaking, lead -acid batteries have the advantages of good reliability, easy raw materials, and cheap prices, and can basically meet the dynamic requirements of electric vehicles than power.

　　But it has three major disadvantages; lower than energy, the quality and volume it occupy is too large;

　　The charging mileage is shorter;

　　The service life is short and the cost of use is too high.
