PVC and SiO2 Separators PVC separators that are made by wet processing are mostly used in lead-acid sealed gel batteries. PVC-SiO2 Separators have higher porosity and more ideal pore sizes than sintered PVC Separators, as well as better puncture and compressive resistance, stronger toughness and greater strength than glass fibre separators. It has a better chemical stability and oxidation resistance than polyethylene PE.

PVC and SiO2 separator properties

1. The PVC/SiO2 separator is characterized by high porosity, a small maximum pore, and high liquid absorption. These characteristics allow the separator to retain the electrolyte easily, and have a rapid penetration rate.
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 and aluminosilicate resistance. Wood, microporous Rubber, Microporous Plastic, and Resin-impregnated Paper are all good materials for separation.

2. The separator is responsible for carrying the sulfuric electrolyte within the battery and sharing all the acid needed to achieve the battery’s rated capacity when the battery is in a lean state. 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 to 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 electrode plate deforming and falling off the active material. This prolongs the battery’s 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.
