Method for improving charging efficiency of lead-acid storage battery

Abstract

The invention discloses a method for improving the charging efficiency of a lead-acid storage battery, and relates to the technical field of storage batteries. The preparation method comprises the following steps: preparing composite powder: carrying out high-temperature sintering treatment on tin powder and zinc powder in a carbon dioxide atmosphere to obtain a sintering material; adding seleniumpowder treated by a coupling agent into the sintering material, carrying out grinding in the presence of a dispersing agent, drying, and carrying out high-temperature heating treatment in an aerobicatmosphere to obtain a high-temperature composite product; grinding the high-temperature composite product in the presence of the dispersing agent, and then sieving the composite product to obtain composite powder; and adding the composite powder into the positive electrode material of the lead-acid storage battery. According to the method for improving the charging efficiency of the lead-acid storage battery, the charging efficiency of the lead-acid storage battery is improved to a certain extent by adding a certain mass fraction of composite powder into lead plaster of a positive electrode of the lead-acid storage battery.
