A high-temperature valve-regulated sealed lead-acid battery

Abstract

The invention relates to a high-temperature valve-regulated sealed lead-acid battery, comprising a battery tank, a positive plate, a negative plate, a separator, and an electrolyte. The plate includes a grid and an active material layer coated in the grid lattice body, The positive plate active material includes lead powder, sulfuric acid, water, short fiber, graphite, Bi2O3, Sb2O3, SnSO4, polyaniline and 4Pb·PbSO4. The lead-acid storage battery of the invention has good high-temperature performance, can ensure the normal use of the storage battery even in the use occasion without air-conditioning facilities, and is especially suitable for use in a high-temperature environment.

Description

Technical field

[0001] The invention relates to the technical field of lead-acid batteries, in particular to a valve-regulated sealed lead-acid battery suitable for use in a high-temperature environment. Background technique

[0002] With the continuous development of communication and energy storage fields, valve-regulated sealed lead-acid batteries are increasingly used in high-temperature environments. For example, the communication base station on the roof of the city, the rural telecommunication repeater station in southern my country, outdoor wind and solar energy storage applications and other high temperature conditions. The valve-regulated sealed lead-acid battery produced by the prior art is used in the above-mentioned high-temperature environment, and its life will be shortened by more than 50%. There are many factors that affect the high-temperature performance of the battery. The main factors are: battery grid alloy, positive active material formula, negative active...
