The AGM separator shall be selected based on its own performance. According to the analysis of the function of the separator in the battery, the AGM separator shall have high acid absorption capacity, small shrinkage after acid absorption, reasonable microporous structure and low resistivity. According to the comprehensive performance requirements of the battery, the AGM separator should also have the characteristics of low impurity content, high tensile strength, fast infiltration speed, etc.

AGM is an absorbable fiberglass mesh battery. Vehicles equipped with engine start-stop function are mostly equipped with AGM and EFB reinforced maintenance-free lead-acid batteries. Compared with ordinary batteries (traditional lead-acid batteries), AGM batteries have more advanced technology and can better solve the problem of frequent engine starts. stress, and the growing electrical load on vehicle batteries.

1. Due to the advantages of its own structure, the loss of lithium battery electrolyte is very small, and there is basically no need to replenish distilled water in time during the service cycle. It also has the characteristics of shock resistance, high temperature resistance, small size and low self-discharge rate. The use cycle is generally twice that of ordinary batteries.

AGM battery refers to the battery whose separator is made of ultra-fine glass wool material. At present, the German department and the American department mainly promote AGM technology. Compared with ordinary batteries, the price is more than three times more expensive, but it has the following advantages:
