What is the AGM isolation board?

Page view
[Abstract]:
AGM is an ultra-fine glass fiber separator.

AGM is an ultra-fine glass fiber separator. The separator is an important component in the production of the battery, and its advantages and disadvantages directly affect the discharge capacity of the battery and the life of the charge and discharge cycle. The separator is an important component of the battery and is not an active substance. In some cases it even plays a decisive role. Its material is an electronic insulator, and its porosity makes it ionic conductive. The resistance of the separator is an important property of the separator. It is determined by the thickness of the separator, the porosity, and the tortuosity of the pores. It has an important influence on the capacity and terminal voltage level of the high-rate discharge of the battery; the stability of the separator in sulfuric acid. It directly affects the life of the battery; the elasticity of the separator can delay the falling off of the active material of the positive electrode; the pore size of the separator affects the degree of short circuit of the lead dendrites. Due to the multi-layer effect of the separator on the performance of the lead storage battery, the improvement of the quality of the separator is accompanied by an improvement in the performance of the lead storage battery. The main function of the separator is to prevent the short circuit of the positive and negative electrodes, but it can not significantly increase the internal resistance of the battery. Therefore, the separator should be porous, allowing free diffusion and ion migration of the electrolyte and having a relatively small electrical resistance. When the active material is somewhat detached, it should not pass through the pores to reach the opposite plate, that is, the pore size should be small, the number of holes should be large, and the total area of the gap should be large; in addition, mechanical strength, acid corrosion resistance, oxidation resistance, and Does not precipitate substances harmful to the plates.
