Valve controlled lead acid accumulator positive lead paste

Abstract

This invention relates to a value controlled lead acid battery positive lead paste prolonging the working life of batteries and devices since it can avoid corrosion to the devices, harm to human bodies or non-uniform mixing which is composed of the components in following weigh percentage taking its weight as the primary standard: short fiber: 0.08-0.5%, water: 5-20% and lead powder for rest.

Description

technical field [0001] The invention relates to a lead-acid accumulator pole plate, especially a lead paste layer on a positive pole plate. Background technique [0002] Valve-regulated lead-acid batteries have been widely used in the fields of backup power, energy storage and power supply. However, the fatal problem of lead-acid batteries at present is mainly the short cycle life of the batteries. The positive active material is the key to restricting this problem. The earliest positive active material used two lead plates as electrodes for repeated charge and discharge, and the lead plates were transformed during the charge and discharge process. It can be said that the positive active material at that time was pure lead. Later, people in the industry used active materials to cover the grid to make battery plates, such as Faure using Pb 3 o 4 As the active material, the lead paste is applied to the lead sheet to make a pole plate. The U.S. patent "...

Problems solved by technology

[0006] The invention mainly solves the problem of short cycle life of batteries with traditional lead paste formulations, and at the same time solves the problems of corrosive equipment, easily injured personnel and uneven lead paste caused by adding sulfuric acid to the traditional lead paste formula. Therefore, the valve of the present invention is provided. Positive lead paste for lead-acid batteries
