Problems solved by technology

This is because it is difficult to find long-term stable substances as additives during the cycle
Secondly, the negative electrode is easy to precipitate hydrogen gas in the later stage of charging, and the addition of additives cannot reduce the hydrogen evolution overpotential of the negative electrode active material.

Abstract

The invention discloses a formula of lead-acid storage battery negative pole diachylon. The lead-acid storage battery negative pole diachylon is prepared from the following components in percentage by weight: 70-90% of lead powder, 3-15% of sulfuric acid, 5-20% of water, 0.05-2% of short fiber, 0.1-20% of polyaspartic acid sodium, and 0.1-10% of carbon nanotube; the sum of the weight percentage of all the components is 100%. According to the invention, the polyaspartic acid sodium is adopted to refine negative pole active substance particles, so as to improve the capacity and the charging receptivity of the negative pole, reduce hydrogen evolution overpotential of the negative pole, and reduce the hydrogen evolution quantity of the negative pole; by adding the carbon nanotube, electric conductivity among active substances of the negative pole can be improved, internal resistance can be reduced, the charging receptivity of the negative pole can be improved, shrinkage of the active substances of the negative pole is reduced, and the service life of the battery is prolonged.

Description

technical field [0001] The invention belongs to the technical field of lead-acid batteries, and relates to a lead-acid battery negative lead paste formula, in particular to a paste-applied valve-controlled sealed lead-acid battery negative lead paste formula. Background technique [0002] With the development of the electric bicycle industry, higher technical requirements are put forward for lead-acid batteries used in electric mopeds. Among them, technical indicators such as low-temperature performance and charging acceptance are related to the negative plate of lead-acid batteries, and it is urgent to improve the performance level of the negative electrode. To meet user requirements. [0003] The traditional lead-acid battery negative electrode paste formula is a mixture of lead powder, sulfuric acid, water, and expansion agents such as lignin, humic acid, and barium sulfate in a certain proportion. The negative plate of the lead-acid battery is composed of very fine spon...
