Problems solved by technology

However, AGM has weak isolation in the state of rich liquid, and it cannot be made into a bag to avoid the micro-short circuit caused by the active material on the battery plate, and the price is relatively high; the composite of PE separator and AGM separator The separator is to add a PE separator layer in the middle of the AGM separator layer. This is compatible with the advantages of the PE separator and the AGM separator, which can slow down the pressure drop of the pole group, will not aggravate the electrolyte stratification, and can effectively reduce lead The short circuit phenomenon caused by dendrite growth, but in the low temperature environment, the PE layer still increases the internal resistance of the battery, which significantly inhibits the low temperature discharge performance. In addition, it also reduces the oxygen recombination efficiency of the battery and increases the battery capacity. water loss

Abstract

The invention discloses a storage battery partition plate and a pregnant solution type storage battery. The partition plate is of a multi-component fiber structure and is formed by processing glass fibers and hydrophobic PE fibers of various diameters and lengths. The PE fiber content of an upper layer and a lower layer of the vertical section structure of the partition plate is the same and is lower than that of an intermediate interlayer. A bag type structure partition plate is adopted for the pregnant solution type storage battery. The storage battery partition plate can have the advantages that a PE partition plate and an AGM partition plate are small in pore diameter and low in resistance and easily made into a bag type, and it can be guaranteed that the pregnant solution type storage battery has good low temperature discharge performance, oxygen compound efficiency and cost performance.

Description

technical field [0001] The invention relates to the technical field of storage batteries, and more specifically, to a storage battery separator and a flooded storage battery. Background technique [0002] The separator is an important component of the battery, not an active substance, but it plays a decisive role in the performance of the battery in some cases. The material of the separator itself is an electronic insulator, and its porosity makes it have ionic conductivity; the resistance of the separator is an important performance of the separator, which is determined by the thickness, porosity, and tortuousness of the hole, and it is important for the high rate of the battery. The discharge capacity and terminal voltage level have an important influence; the stability of the separator in sulfuric acid directly affects the life of the battery; the elasticity of the separator can delay the shedding of the positive active material; the pore size of the separator affects the...
