Problems solved by technology

This white coarse-grained lead sulfate has poor electrical conductivity and is difficult to dissolve. It can no longer be reduced to spongy lead and lead dioxide during charging, forming irreversible salinization (sulfurization), resulting in a decrease in battery capacity and a cycle cycle. shortened lifespan

Abstract

The invention discloses an additive of colloidal electrolyte, which contains the following components with the following weight percentages: 0.2 to 3 percent of phosphoric acid, 1 to 2 percent of sodium sulfate and 0.1 to 1 percent of stannous sulfate. The additive contains the phosphoric acid, the sodium sulfate and the stannous sulfate; after the phosphoric acid is added into the colloidal electrolyte, the softening rate of the anode active material PbO2 of a accumulator can be reduced, and the PbO2 loss can be reduced, thereby prolonging the cycle life of the accumulator and reducing the plate sulfation when the accumulator is kept after being completely discharged. The sodium sulfate and the stannous sulfate added into the colloidal electrolyte of the accumulator can effectively inhibit the accumulator sulfation.

Description

technical field [0001] The present invention relates to the field of storage batteries, in particular to a colloidal electrolyte of a colloidal storage battery. Background technique [0002] Colloidal battery refers to a battery that uses colloidal electrolyte as a medium instead of sulfuric acid. Solid state when moving. When the battery is charged, due to the increase in the concentration of sulfuric acid in the electrolyte, it is "thickened" and accompanied by cracks. The "electrolyzed water" reaction in the later stage of charging causes the oxygen generated by the positive electrode to be absorbed by the negative electrode through the countless cracks, and further It is reduced to water, so as to realize the battery sealing cycle reaction. During discharge, the sulfuric acid concentration in the electrolyte decreases to make it "thinned", and it becomes the thin gel state before filling the battery. Therefore, the gel battery has a "maintenance-free" effect. [0003...
