Problems solved by technology

The existing valve-regulated sealed battery adopts traditional technology and structure. The above-mentioned factors are not scientific and reasonable. Generally, it works in an air-conditioned and constant temperature environment, resulting in a large amount of energy consumption. The working temperature does not exceed 28°C, otherwise the life is greatly shortened. Can not meet the requirements of high temperature environment

Embodiment 1

[0020] Embodiment 1: Take the commonly used 2V500Ah battery as an example:

[0021] 1. Plate production:

[0022] Positive grid 7 is cast by using high-tin and low-calcium lead alloy (the content of tin is 2.0%, the content of calcium is 0.08%, and the balance is lead);

[0023] In addition to lead powder, 0.8% polyester fiber, 8.0% sulfuric acid (1.4g / ml), 13% deionized water, 0.5% graphite, 0.08% Bi 2 o 3 , 0.1% Sb 2 o 3 , 0.08% SnSO 4 , 0.6% polyaniline, 0.6% 4Pb·PbSO 4 . Lead powder, polyester fiber, graphite, Bi 2 o 3 , Sb 2 o 3 , SnSO 4 , polyaniline, 4Pb·PbSO 4 Perform dry mixing first, then add deionized water in the prescribed amount for wet mixing, and then slowly add the sulfuric acid solution in the prescribed amount after wet mixing, and fully stir to form the positive lead paste 6, which is filled and coated on the positive grid 7, and cured After drying, a positive plate is formed;

[0024] The negative grid 5 is cast by ordinary lead-calcium allo...

Embodiment 2

[0029] Embodiment two: prepare 2V500Ah battery by the method for embodiment one, difference is:

[0030] The tin content of the positive grid is 1.2%, and the calcium content is 0.04%;

[0031] In addition to lead powder, 1.0% polyester fiber, 10% sulfuric acid (1.4g / ml), 11% deionized water, 0.2% graphite, 0.04% Bi 2 o 3 , 0.05% Sb 2 o 3 , 0.04% SnSO 4 , 0.2% polyaniline, 0.2% 4Pb·PbSO 4 ;

[0032] In the negative electrode active material, except lead powder, also add polyester fiber relative to lead powder quality 1.0%, 11% sulfuric acid (1.4g / ml), 11% deionized water, 0.4% lignin, 0.4% Humic acid, 0.2% acetylene black, 0.1% indulin, 0.1% anisaldehyde;

[0033] SiO 2 The weight percentage relative to the electrolyte is 0.5%.

[0034] The battery prepared in the above example was subjected to a high-temperature accelerated float charge life test. The test procedure was: place the battery in an environment of 60±2°C, charge it continuously for 30 days at a float volt...

Abstract

The invention relates to a high-temperature valve regulated sealed lead-acid storage battery. The high-temperature valve regulated sealed lead-acid storage battery comprises a battery groove, a positive-electrode plate, a negative-electrode plate, a partition plate and an electrolyte. Each electrode plate comprises grids and an active material layer applied into a grid body of the grids. The active materials in the positive-electrode plate comprise lead powder, sulfuric acid, water, short fibers, graphite, Bi2O3, Sb2O3, SnSO4, polyaniline and 4Pb.PbSO4. The lead-acid storage battery is good in high-temperature performance, can be normally used even on using occasions without air conditioner facilities and is particularly suitable for being used under high-temperature environments.

Description

[0001] technical field [0002] The invention relates to the technical field of lead-acid batteries, in particular to a valve-controlled sealed lead-acid battery suitable for use in high-temperature environments. Background technique [0003] 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, under high temperature conditions such as communication base stations on the top of urban buildings, rural telecom repeaters in southern my country, and outdoor wind and solar energy storage applications. The valve-regulated sealed lead-acid battery produced by the prior art is used in the above-mentioned high-temperature environment, and the service life will be shortened by more than 50%. There are many factors that affect the high temperature performance of batteries, the main factors are: battery grid alloy, positive active material formulation, n...
