Negative lead cream of valve-controlled sealed plumbous acid accumulator for starting vehicle and production thereof

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)...
