Abstract

The invention belongs to the field of storage batteries and specifically relates to an acid mist absorbing material for a battery formation device. The acid mist absorbing material is a spherical particle which is formed by taking a porous inorganic-organic compound particle as a spherical frame and an acrylate polymer as a coating agent. According to the invention, the problem of unsatisfying effect of the acid mist absorbing material in the prior art can be solved; an inorganic-organic framework particle is capable of achieving excellent supporting and circulating effects; the inorganic-organic framework particle is combined with the acrylate polymer having a water-absorbing property, so as to form a water film absorbing structure.

Description

technical field [0001] The invention belongs to the field of accumulators, and in particular relates to an acid mist absorbing material used in a battery formation device. Background technique [0002] In the process of battery manufacturing, it is necessary to activate the positive and negative materials inside the plate through a certain charging and discharging method, and transform it into a state of charge, so as to improve the battery's charge and discharge performance, self-discharge, storage and other comprehensive performance. This chemical reaction process It is called the formation process, and the formation process is completed in the battery formation equipment, specifically in the water tank of the formation equipment. During the battery formation process, a large amount of acid mist will be generated, which will pollute the environment, and the acid liquid is highly corrosive and conductive, which may easily cause fire accidents. [0003] In the prior art, th...
