  The positive electrode material of lead-acid battery is mainly composed of PbO2, and the negative electrode material is mainly composed of Pb. Under normal circumstances, the electrolyte is dilute sulfuric acid. We all know that the battery water of lead-acid batteries has corrosion function because of the electrolyte material. The standard voltage of a lead-acid battery is 2V. Generally, the discharge reaches 170Wh/kg in theory, but in actual use we can only reach 35-45Wh/kg, so the loss is very large. In addition, due to the conductivity of the electrolyte, Lead-acid batteries can no longer be charged with high current when self-discharged. Generally, the charging limit of lead-acid batteries is below 0.3C.

  However, after so many years of development, the process development of lead-acid batteries has been very mature, there is no technical bottleneck, and the repeated utilization rate of its materials can reach 75%. This is the reason why our daily lead-acid batteries are cheap to replace with new batteries. This is also a point that the majority of users attach importance to. However, the materials of lead-acid batteries have certain environmental pollution conditions, which are also harmful to the body. This is unavoidable because of the limited materials. So sometimes the electrolyte leakage during use will cause great pollution to the human body and the environment.

  So, in general, the life of lithium batteries is about ten years and lead-acid batteries are about four years. The price of lithium batteries is about twice that of batteries. How to choose depends on your own needs. If you need it Welcome to call our Guangdong lithium battery manufacturer.
