Abstract

The invention provides a formation method of a lead-acid storage battery. The method comprises the steps of firstly, carrying out multi-stage constant-current charge and constant-current discharge, and then carrying out constant-current charge, wherein the total formation time is 45h-70h, and the charge current and the discharge current are 0.05-0.2 C10. The method is used for the formation of the valve-regulated sealed lead-acid storage battery for communication; the polarization phenomenon of the battery in the formation process can be effectively relieved by the multi-stage charge and discharge under the condition that equipment investment is not increased, so that the charging efficiency and the formation efficiency are improved, and the battery capacity is guaranteed.

Description

[0001] technical field [0002] The invention relates to a method for forming a lead-acid battery, which belongs to the technical field of lead-acid battery production. Background technique [0003] After the lead-acid battery is assembled, it needs to be acidified and formed. The purpose of the formation is to convert the positive lead paste into lead dioxide, and the negative lead paste into spongy lead, so that the battery has electric performance and can accept the charge of electric energy. and release the electrical energy. At present, fixed valve-controlled sealed lead-acid batteries for communication basically adopt the internal formation process, which is carried out in accordance with the charging-discharging-charging steps. Due to the small number of charging and discharging and the influence of the polarization of the plate surface, the formation time takes between 96 and 120 hours. The formation efficiency is low, which seriously affects the battery production ...
