AGM separator is a kind of ultra-fine glass fiber separator.

The separator is an important part of battery production, and its pros and cons directly affect the battery's discharge capacity and charge-discharge cycle life.

The battery pack has nothing to do with the function of the active material. Sometimes, it even played a decisive role. It is an insulating material in itself, and its porosity makes it ionic conductivity. The resistor is an important performance index of the separator. This point is related to the separator thickness, porosity, ripple and other factors, and has an important impact on the high discharge capacity and terminal voltage of the battery; the stability of the separator directly affects the life of the battery; the elasticity of the separator will delay the shedding of the positive active material ; The aperture of the separator will affect the short-circuit degree of the lead dendrites.

Every time the quality of development is improved, it will be accompanied by the improvement of battery performance, and the impact of separators on all aspects of lead-acid batteries. Its main function is to prevent short-circuiting of the positive and negative electrodes, and the internal resistance of the battery is significantly increased. According to this method, the separator should be porous, allowing the electrolyte to diffuse freely, ion migration, and low resistance. This is a separation of active substances, so that some cannot reach the back panel through fine holes, that is, the pore size is small, the number of holes is large, and the total gap is large; in addition, it should have good mechanical strength, acid corrosion resistance, oxidation resistance, and no precipitation. Hazardous substances.

The structure and performance of FRP partitions.

The partition wall is made of glass fiber, with a diameter of 0.5 to 4 microns, without any adhesive. The glass fiber paper prepared by the papermaking method has a mat-like structure and is a small, curved free channel composed of disordered glass fibers. It is better than ordinary batteries in many ways. Its main features are: First, it has fast liquid absorption speed and strong water absorption capacity; second, it absorbs and maintains the electrolyte required by the battery's rated capacity, and has a high liquid absorption rate during the entire use process; second, it has large surface area and porosity. high. When the electrolyte is insufficient, the oxygen generated in the positive electrode can diffuse to the negative electrode through the separator and be combined with the sponge lead. 3. Small pore size to prevent battery short circuit and dendrite penetration; 4. Less harmful impurities; 5. Good acid resistance and oxidation resistance; 6. Low resistance.
