Abstract

The present invention relates to a zinc-manganese dry battery, particularly to that 3.765% of high temperature calcined aluminum silicate salt milled into fine powder with removed impurities is added in the production of the electric core materials of positive electrodes and dielectrics of the zinc-manganese dry battery. The present invention has the advantages that the present invention eliminates the pollution of harmful substance caused by concentrated water discharge and the use of ammonium chloride, zinc chloride, mercuric chloride, etc. in work processes, and mercury damage, greatly enhances the utilization rate of positive pole active substance and causes the capacity of the zinc-manganese dry battery to exceed the 2.1 times of the Chinese standard.

Description

No mercury high-energy zinc-manganese cell
The present invention relates to a kind of zinc-manganese dioxide dry cell, particularly in producing the positive pole core material of zinc-manganese dioxide dry cell, a kind of high-performance of adding aluminium silicate salt, the dry cell of high power capacity.
The zinc-manganese dioxide dry cell of Xiao Shouing in the market, owing to use zinc chloride, sal-ammoniac and mercury chloride, thereby easily generate in the course of the work and a kind ofly because of assembling the harmful substance after the draining pH value is constantly increased, separator is done solid; Seriously hinder the reaction energy of positive active material, influenced the useful life of battery.
The purpose of this invention is to provide a kind of elimination harmful substance, the reaction energy of the utilance of increase manganese dioxide, interpolation aluminium silicate salt, increase active material is stablized pH value, and separator is difficult for doing solid new material.
Production technology of the present invention is basic identical with the production technology of the zinc-manganese dioxide dry cell of selling in the market, different is in its positive pole core material, add 3.765% through high-temperature calcination, wear into fine powder, remove aluminium silicate salt behind its impurity (separator make two layers of paper of paste bag make) with this liquid.
Advantage of the present invention is: eliminated a kind of because of the harmful substance after the assembly draining because of what use materials such as ammonium chloride, zinc chloride, mercury chloride to generate in the course of the work; Improved the utilance of positive active material significantly, eliminated pollution of " mercury " evil, made the capacity of zinc-manganese dioxide dry cell surpass 2.1 times of GB.
