Reagents added to battery separators to prevent liquid corrosion
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.
In order to improve the sealing reaction efficiency of valve-regulated lead-acid batteries, the battery separator should be able to provide enough oxygen channels when the battery is charging, so that the oxygen separated from the positive plate can smoothly pass through the separator to the negative plate, and be converted into water to realize oxygen circulation. , which requires the BATTERY SEPARATOr to have a reasonable microporous structure, and also requires the battery design to determine the appropriate acid absorption saturation of the separator. The BATTERY SEPARATOR should be porous to allow electrolyte penetration, and should have good acid and alkali resistance. The battery separator is made into a bag shape, which is tightly wrapped on the outside of the positive plate to prevent the active material from falling off.
If the battery is not charged in time after self-discharging, it is easy to vulcanize the plate over time. After the battery separator is vulcanized, the coarse lead sulfate is distributed on the surface of the active material, blocking the voids of the active material, making it difficult for the electrolyte to penetrate, and increasing its resistance. During the use of the BATTERY SEPARATOR, attention should be paid to the height of the electrolyte liquid level and keep it within the specified value range. When not in use for a long time, the battery should be removed from the tractor and stored in a dry room; when the temperature drops, lead sulfate will precipitate from the saturated electrolyte and crystallize to the nearby plates.
