Storage battery colloidal electrolyte and preparation method thereof

Abstract

The invention relates to a storage battery colloidal electrolyte containing natural acicular nanocrystalline or microfiber, mainly comprising the following components in weight ratio: 3.0-12 percent of gelatinizing agent (silicon-contained gel), 0.01-0.1 percent of flow improver, 5.0-13.8 percent of complex additive and the balance of electrolyte (a sulfuric acid dilute solution), wherein the flow improver is the natural acicular nanocrystalline or microfiber. The colloidal electrolyte has good thixotropic flowability and gel stability and low colloidal kinetic viscosity; the glue pouring efficiency of the colloidal electrolyte and the immersional wetting effect of the colloidal electrolyte on a partition board and a polar plate are improved, and the resistance of the colloidal electrolyte is reduced; and therefore, the colloidal electrolyte can be used for assembling storage batteries with different applications and different modes.

Description

technical field

[0001] The invention relates to an electrolyte used in storage batteries, in particular to a colloidal electrolyte. Background technique

[0002] The application of gel electrolyte instead of liquid electrolyte is an important new technology for lead-acid batteries. The colloidal electrolyte in the gel state does not flow in the battery, so it is not easy to leak acid, which can effectively prevent the active material from falling off, effectively inhibit the growth and penetration of lead dendrites, reduce battery self-discharge, and prolong battery life. Gel battery mainly adopts valve control technology, which is a kind of sealed battery. Compared with AGM valve-regulated batteries, gel batteries have obvious advantages during use, which is beneficial to prolong the cycle life of batteries. However, since the viscosity of the colloidal electrolyte used in the colloidal battery is much higher than that of the ordinary sulfuric acid electrolyte, this bring...
