Separators for PVC and SiO2. PVC separators that are made by wet processing are mostly used in lead-acid sealed gel batteries. PVC-SiO2 Separator has higher porosity compared to sintered PVC separator. It also has more ideal pore sizes, greater puncture resistance, superior compressive strength as well as stronger toughness compared to 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, a small maximum pore, and high liquid absorption. These characteristics allow the separator to retain electrolytes, have a rapid penetration rate, and enhance retention of active materials.
2. The wet elastic is strong and can provide electrolyte to the plate while keeping the ion conductivity unblocked.

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 electrode plate receives all the sulfuric required to meet the battery’s rated capacity. 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 be able, when the battery charges, to provide sufficient oxygen channels so that the oxygen precipitated by the positive plate is able to pass through the separator and reach the negative plate 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. In the valve-regulated, lead-acid batteries, the separator prevents the active material from the electrode plate falling off, and also the electrode plate deforming. This prolongs the service life. It is necessary that the separator shrinks after being injected with sulfuric acid.

5. Internal resistance includes the resistance of both the separator and 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.
