Abstract

The invention discloses a preparation method of a lead-acid storage battery negative plate. The preparation method comprises the following steps: (1) weighting lead powder, a carbon source, a zirconium source, barium sulfate, lignin, fibers, dilute sulphuric acid and distilled water which serve as raw materials in a mass ratio of 25:(0.1-0.3):(0.05-0.4):(0.1-0.25):(0.05-0.25):(0.005-0.02):(3-5):(4-7) for standby application; (2) preparing lead plaster; (3) plating; (4) forming. The preparation method has the advantages that a right amount of zirconium compound is added to a negative plate, so that the discharge capacity can be improved by 3-5%, meanwhile, the hydrogen evolution electric potential is remarkably negatively shifted, so that hydrogen is difficult to separate out, and the consumption of acid in a cyclic process is effectively reduced.

Description

technical field [0001] The invention relates to a preparation method of a lead-acid storage battery negative plate containing a zirconium additive, and belongs to the technical field of energy materials. Background technique [0002] Lead-acid batteries have the advantages of abundant raw materials, simple production process, mature technology, low price, and stable electrical performance. However, due to the low utilization rate of active materials, lead-acid batteries have low quality and specific energy. With the expansion of the application field of lead-acid batteries, people put forward higher requirements for their electrical properties, such as high rate charge and discharge, low temperature characteristics, high temperature resistance characteristics and service life. One of the most effective ways to solve these problems is to add an appropriate amount of additives to the active substance without changing the existing process conditions. Although there are many st...
