Tubular lead-acid battery positive pole squeezing cream and preparation method thereof

Abstract

The invention discloses a tubular lead-acid battery positive pole squeezing cream. The positive pole squeezing cream is composed by the following raw materials according to the weight percentage of chemical compositions of 55%-65% of Barton-type lead powder with 70%-77% of oxidizability, 11%-15% of lead tetroxide, 1%-3% of lead peroxide, 0.11%-0.13% of carbon black, 11%-15% of de-ionized water, 6%-10% of sulfuric acid with 50%-55% of weight concentration. The invention also provides a preparation method of the tubular lead-acid battery positive pole squeezing cream. The squeezing cream has higher mass ratio energy and volume ratio energy, and is suitable for market requirements of tubular lead-acid batteries.

Description

technical field [0001] The invention relates to a lead-acid storage battery, in particular to a tube-type lead-acid storage battery anode extrusion paste and a preparation method thereof. Background technique [0002] At present, the positive electrode active material filling methods of tubular lead-acid batteries are roughly divided into three types: powder filling, grouting and paste extrusion. Powder filling is to use the high-frequency vibration of the vibrating motor to fill the active material into the positive tube. The consistency of the positive plate manufactured by this method is difficult to control, and due to the high-frequency vibration, the production noise is large and the environment is seriously polluted; the grouting is to The active material is liquefied and filled into the positive electrode pipe with a grouting machine. This method has little environmental pollution, but because of the liquefaction of the active material, its compacted density is relat...

Problems solved by technology

Powder filling is to use the high-frequency vibration of the vibrating motor to fill the active material into the positive tube. The consistency of the positive plate manufactured by this method is difficult to control, and due to the high-frequency vibration, the production noise is large and the environment is seriously polluted; the grouting is to The active material is liquefied and filled into the positive electrode pipe with a grouting machine. This method has little environmental pollution, but because of the liquefaction of the active material, its compacted density is relatively reduced, and the capacity of the positive plate produced is not as good as that of powder filling; The active material is mixed with corresponding auxiliary materials and filled into the positive electrode pipe with a certain pressure. This method has little environmental pollution and can control the compacted density of the active material. However, it has high requirements for the formula and manufacturing process, so only Only with reasonable formula and perfect preparation method can we meet the growing market demand
