Separators for PVC and SiO2 PVC separators that are made by wet processing are mostly used in lead-acid sealed gel batteries. PVC-SiO2 Separators have higher porosity and a better pore size distribution than sintered PVC Separators. They also have a better puncture resistant, greater compressive strength, as well as tensile strength that is stronger than glass fibre separators. It is better at oxidation resistance, chemical stability and toughness than polyethylene PE.

PVC and SiO2 separator properties

1. The PVC/SiO2 separator is characterized by high porosity, small pores and high liquid absorption rates. These characteristics allow the separator to retain electrolytes, increase the retention rate of active materials, and extend the battery’s life.
2. The plate’s wet elasticity can provide a stable electrolyte and maintain the ion conductivity.

3. The “acid-strategization” phenomenon can be effectively prevented by a battery with strong liquid transfer abilities.

4. Based on the glass fiber. By adding organic fibers, the PVC/SiO2 separation is enhanced in terms of tensile strength and other performance indicators.

Application of the PVC-SiO2 separation in batteries:

1. The positive and the negative plates are placed close to each other, but should not be in direct contact. A separator between the plates is used. The PVC-SiO2 should be porous to allow electrolyte into the separator, and have good acid resistance and alkali tolerance. Wood, microporous Rubber, Microporous Plastic, and Resin-impregnated Paper are all good materials for separation.

2. The battery separator is responsible for carrying the sulfuric electrolyte within the battery. In the lean state, the separator shares the entire amount of sulfuric required by the battery to meet its rated capacity with the electrode plate. For this to work, the separator needs to be large enough to absorb the sulfuric acids. Also, the battery must have enough space to accommodate the separator.

3. The PVC-SiO2 separation should provide sufficient oxygen channels to allow the oxygen that precipitates from the positive plate to pass through it to the negative, where it can be converted into oxygen. cycle. The separator must have a reasonably microporous surface, and the acid saturation of the separator must be determined at the time the battery is being designed.

4. The separator is used in lead-acid batteries with valve regulation to prevent the active material from falling from the electrode plate and the electrode from deforming. This prolongs the service life. It is necessary that the separator shrinks after being injected with sulfuric acid.

5. The internal resistance of a battery includes the resistance of a battery separator as well as the resistance that is formed when the separator contacts the plate. It is necessary that the separator has a low resistance and also be put under greater pressure when designing the battery. So, the PVC/SiO2 separation is in contact with the poleplate, and resistance is reduced at this point.
