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

[0019] Example 1: Take a 2V500Ah battery with common specifications as an example:

[0020] 1. Plate production:

[0021] Use high tin and low calcium lead alloy (the content of tin is 2.0%, the content of calcium is 0.08%, the balance is lead) to cast the positive grid 7;

[0022] In addition to the lead powder, the positive active material also contains 0.8% polyester fiber, 8.0% sulfuric acid (1.4g / ml), 13% deionized water, 0.5% graphite, and 0.08% Bi relative to the mass of the lead powder. 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 Dry mixing first, then add deionized water of formula for wet mixing. After wet mixing is evenly mixed, slowly add formula of sulfuric acid solution, stir it to form positive lead paste 6, fill it on positive grid 7, and solidify After drying, a positive electrode plate is formed;

[0023] Use ordinary lead calcium alloy to ca...

Embodiment 2

[0028] Example 2: Prepare a 2V500Ah battery according to the method of Example 1. The difference is:

[0029] The tin content of the positive grid is 1.2%, and the calcium content is 0.04%;

[0030] In addition to the lead powder, the positive active material also contains 1.0% polyester fiber, 10% sulfuric acid (1.4g / ml), 11% deionized water, 0.2% graphite, and 0.04% Bi relative to the mass of the lead powder. 2 O 3 , 0.05% Sb 2 O 3 , 0.04% SnSO 4 , 0.2% polyaniline, 0.2% 4Pb·PbSO 4 ;

[0031] In addition to the lead powder, the negative active material also contains 1.0% polyester fiber, 11% sulfuric acid (1.4g / ml), 11% deionized water, 0.4% lignin, and 0.4% relative to the mass of lead powder. Humic acid, 0.2% acetylene black, 0.1% indulin, 0.1% anisaldehyde;

[0032] SiO 2 The weight percentage relative to the electrolyte is 0.5%.

[0033] The battery prepared in the above embodiment was subjected to a high-temperature accelerated floating charge life test. The test procedure is: p...

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...
