The battery separator has a small pore size and high porosity, which is easy to retain the electrolyte, has a good liquid absorption rate and a fast penetration rate, and can effectively enhance the retention of active substances and prolong the battery life. The battery separator can stably supply electrolyte to the pole plate and keep the ion conduction smooth. The strong liquid transfer ability can effectively prevent the phenomenon of acid stratification in the battery. The glass fiber is mainly used, and a certain amount of organic fibers are mixed to enhance the tensile strength of the separator and optimize other performance indicators.

AGM is an absorbable fiberglass mesh battery. Vehicles equipped with engine start-stop function are mostly equipped with AGM and EFB reinforced maintenance-free lead-acid batteries. Compared with ordinary batteries (traditional lead-acid batteries), AGM batteries have more advanced technology and can better solve the problem of frequent engine starts. stress, and the growing electrical load on vehicle batteries.

During the use of the battery, the problem of swelling and cracking, or even explosion, may occur, whether it is a new battery or an old battery. The main reasons for battery inflation are as follows:
a) The vent on the tank filler cap is blocked or blocked
During the charging process of the battery, especially at the end of the charging process, a large amount of explosive gas will be generated inside the battery. If the vent on the battery filler cap is blocked or blocked at this time, these gases will not be discharged in time, so they will accumulate in the battery shell, and the pressure will increase, finally the battery will swell.
b) When the charging current of the battery is too high or the charging time is too long, the temperature of the electrolyte will increase rapidly, and a large amount of gas will be generated, which will loosen and fall off the active substances on the battery plate, causing the battery to swell.

The battery separator is an integral part of the battery. In the valve-regulated lead-acid battery, the battery separator can prevent the active material of the plate from falling off and the deformation of the plate, and prolong the service life of the battery. It is required that the battery separator shrinks less after the sulfuric acid is injected, and the battery separator is also required to be in a higher pressure state when the battery is designed. The resistance formed by the resistance of the battery separator and the contact of the electrode plate is a component of the internal resistance of the battery. The battery separator itself has a low resistivity, and the battery separator is also required to be in a high pressure state during battery design.

One of the obvious differences between dry cell batteries and wet cell batteries is that the electrolytes of wet cell batteries are liquid, while the electrolytes of dry cell batteries are colloidal or solid. They have different advantages and disadvantages due to different manufacturing materials. So which is better between dry cell batteries and wet cell batteries?

Generally speaking, the batteries used in automobiles are mainly divided into two types: water-added lead-acid batteries and maintenance-free lead-acid batteries. At present, most models use maintenance-free lead-acid batteries. However, there are also many Japanese cars, including some high-end models, and some use non-maintenance-free lead-acid batteries.

The battery safety valve, also known as the battery exhaust valve, is a valve that acts as a safety protection valve on a valve-controlled battery. When the battery is working, the internal pressure of the battery is gradually increased due to the internal reflection of the released gas. When the pressure reaches the valve opening threshold, the safety valve automatically opens to discharge the gas. After the internal pressure of the battery drops to the valve closing threshold, the safety valve automatically closes. At the same time, during this process It can prevent external gas from entering the battery and acid splashing in the battery. It can avoid the bulging and explosion caused by excessive pressure in the battery or the oxidation failure of the battery reaction solution caused by the entry of external gas into the battery.

1. Due to the advantages of its own structure, the loss of lithium battery electrolyte is very small, and there is basically no need to replenish distilled water in time during the service cycle. It also has the characteristics of shock resistance, high temperature resistance, small size and low self-discharge rate. The use cycle is generally twice that of ordinary batteries.
