Embodiment 1

[0021] Example 1: 100kg of lead powder with a PbO content of 75% to 85% is added to the paste mixer, and 0.05kg of fiber, 0.2kg of acetylene black, 0.5kg of ultrafine barium sulfate, and 0.1kg of sodium lignosulfonate are added simultaneously , 0.6kg of humic acid, stir the above materials evenly, then add 10kg of purified water, after mixing evenly in wet state, quickly pour in the density of 1.400g / cm 3 (25°C) sulfuric acid solution 10kg, during the mixing process, the paste temperature is controlled to be less than 65°C, the reaction is uniform and the temperature drops below 45°C, and the paste can be used. The so-called ultrafine barium sulfate refers to powders with a particle size of less than 30 microns.

Embodiment 2

[0022] Example 2: Add 100kg of PbO content of 75% to 85% lead powder into the paste mixer, and add 0.05kg of fiber, 0.25kg of acetylene black, 0.7kg of ultrafine barium sulfate, and 0.2kg of sodium lignosulfonate , 0.55kg of humic acid, stir the above materials evenly, then add 11kg of purified water, after mixing evenly in wet state, quickly pour in the density of 1.400g / cm 3 (25°C) sulfuric acid solution 9kg, during the mixing process, the paste temperature is controlled to be less than 65°C, the reaction is uniform and the temperature drops below 45°C, and the paste can be used.

Embodiment 3

[0023] Embodiment 3: 100kgPbO content is that the lead powder of 75%~85% is added in paste machine, add the fiber of 0.06kg, 0.4kg acetylene black, the superfine barium sulfate of 0.8kg, the sodium lignosulfonate of 0.14kg simultaneously , 0.8kg of humic acid, stir the above materials evenly, then add 12kg of net homogenized water, after mixing evenly in wet state, quickly pour in the density of 1.400g / cm 3 (25°C) sulfuric acid solution 8kg, during the mixing process, the temperature of the mixing paste is controlled to be less than 65°C, the reaction is uniform and the temperature drops below 45°C, and the paste can be used.

Abstract

The lead plaster for use in battery anode comprises 100 proportion lead powder, 0.05-0.06 proportion fabric,0.2-0.4 proportion acetylene black,0.5-0.8 superfine barium sulphate, 0.5-0.8 proportion humic acids, and 0.1-0.2 proportion ligninsulfonic acid . The oxidation-proof anode ingredient is selected to improve charging property and starting ability at low temperature and attain more cycling times.

Description

technical field [0001] The invention relates to a storage battery material and a preparation method, in particular to a valve-controlled sealed lead-acid storage battery negative lead paste for automobile starting, which belongs to the technical field of storage batteries. Background technique [0002] With the rapid development of the automobile industry, the performance requirements of lead-acid batteries are getting higher and higher. As a high-end product of lead-acid battery, valve-regulated sealed battery has been used and researched in the past 20 years. Its actual performance, stability, life and other characteristics have made great progress, and its application fields are more extensive. At present, vehicles using valve-regulated batteries as backup power sources have been mass-produced abroad. For example, Toyota and Honda in Japan use 42V system vehicles using valve-regulated sealed batteries (for starting, lighting, ignition, energy storage, and auxiliary power)...
