Selecting the right battery separator is essential to ensure the performance and safety of your battery. Battery separators are crucial components that prevent the short-circuiting of a battery by separating the positive and negative electrodes while allowing the flow of ions. Here are some key factors to consider when choosing a battery separator:

Lead-acid batteries are mainly composed of negative elemental lead, positive lead dioxide, electrolyte and separators. The PE separator is between the positive and negative plates of the battery, which can prevent the positive and negative plates from directly contacting and discharging to cause short circuit. At the same time, there are a certain amount of holes on the separator to ensure the passage of positive and negative ions and prevent open circuit. Therefore, the importance of the separator is no less than that of the positive and negative plates of the battery. At present, it is generally believed that the explosion accident caused by the short circuit of the lead-acid battery is mainly caused by the aging of the separator.

In order to prolong the cycle life of PE battery separator, it is necessary to ensure that the plate is always in a compressed state during the battery cycle. The separator of PE battery will shrink after the battery is filled with acid or the battery is dehydrated, and the contraction of the separator reduces the pressure between the plates, thus shortening the cycle life of the battery. The bonding force between superfine glass fibers in the separator of PE battery is very small. When the surface tension of water is greater than the bonding force between fibers, the bonding force between superfine glass fibers will be destroyed; The elasticity of the superfine glass fiber in the separator of PE battery is not good enough, so that it cannot be restored to its original state after being compressed.

1. Compared with many traditional separators, PE separator has the strongest oxidation resistance from the material point of view. However, due to its soft texture and thin base thickness, PE separator is deformed during battery charging and discharging, which is easy to cause heat loss and aggravate the thermal oxidation process of the separator.

PE battery separator has many effects on the performance of lead battery. Every improvement of separator quality is accompanied by the improvement of lead battery performance. The main function of PE battery separator is to prevent short circuit between positive and negative electrodes, but it cannot significantly increase the internal resistance of the battery. PE battery separator is mainly used to prevent short circuit between positive and negative electrodes, but it cannot significantly increase the internal resistance of the battery. Therefore, the separator should be porous, allowing free diffusion of electrolyte and ion migration, and has a relatively small resistance. PE battery separator shall not reach the opposite electrode plate through fine holes, that is, the hole diameter shall be small, the number of holes shall be large, and the total area of the gap shall be large.

PE separator is a new type of separator after rubber separator, glass fiber separator and polyethylene (PVC) separator. It has the advantages of high porosity, small pore size, low resistance, good toughness and sealability. Prevent edge short circuit, reduce active material shedding, and improve battery life.

In an acidic environment, the PE separator will accelerate its own aging as the temperature rises. After use, the PE separator has different degrees of grid indentation on the contact surface of the front plate. It is obvious that all parts of the separator are oxidized and damaged. It exists in the direction of the indentation, and the direction in which the separator is embrittled and falls off to form holes is the direction of the grid. The microstructure of the PE separator changed significantly before and after oxidation, and a large number of lead sulfate particles adhered to the inside and outside of the oxidized PE separator; the oxidation of the PE separator usually occurred in the direction of the positive plate, because the positive plate was charged during the charging process. During the process, the temperature of the electrode plate is continuously increased, and the temperature of the solution is also continuously increased.

In the 1950s, starting batteries mainly used wooden separators. Because they had to be used in wet conditions, the negative plates were easily oxidized, and the initial charging time was long, and they could not be used for dry-charged lead batteries. In particular, wooden separators are not resistant to oxidation and corrosion in sulfuric acid, resulting in short battery life. In order to improve the life of lead-acid batteries, it is proposed to use wood separators and glass wool as separators, which doubles the life of the battery, but the internal resistance of the battery increases, which has an adverse effect on the battery capacity and starting discharge, and can also meet the standard requirements at that time.
