Problems solved by technology

[0004] The existing coating materials are mainly made of metal lead and auxiliary materials of the coating materials. Lead is distributed in the auxiliary materials, and in the actual use process, lead is easy to accumulate, precipitate, and delaminate in the auxiliary materials, which greatly affects the coating. electrical conductivity of the material
At the same time, during the use of the battery, hydrogen and oxygen will be generated, and the gas will accumulate in a large amount inside the coating material, thereby reducing the contact area between the conductive material and sulfuric acid, resulting in poorer charging effect of the battery

Embodiment 1

[0035] Step 1: Take 6g of polyacrylamide powder, add water to dissolve it, then add 40g of copper-zinc mixed powder, 10g of activated carbon powder, 4g of starch and 0.5g of glucose oxidase, and stir until it is evenly stirred to obtain mixed colloid 32.

[0036] Step two:

[0037] take as figure 1 As shown in the tubular first mold, the first mold includes a first inner shell 11 and a first outer shell 1, the first outer shell 1 is sleeved outside the first inner shell 11, and between the first inner shell 11 and the first outer shell 1 A first cavity 13 is formed, and a plurality of through holes 12 are opened on the first shell 1 , and the through holes 12 are arranged along the length direction of the first shell 1 .

[0038] take as figure 2 The shown tubular second mold, the second mold includes a second inner shell 23 and a second outer shell 22, the second outer shell 22 is sleeved outside the second inner shell 23, between the second inner shell 23 and the second o...

Embodiment 2

[0048] The difference between this example and Example 1 lies in that the quality of each raw material is different, and the raw materials of Example 2 are selected according to Table 1, and the production steps of Example 1 are repeated.

Embodiment 3

[0050] The difference between this embodiment and the foregoing embodiments lies in that the quality of each raw material is different. According to Table 1, the raw materials of Embodiment 3 are selected, and the manufacturing steps of Embodiment 1 are repeated.

Abstract

The invention relates to the technical field of storage battery manufacturing, and concretely relates to an alloy coating material. The alloy coating material comprises, by mass, 40-60 parts of copperand zinc mixed powder, 10-20 parts of active carbon, 6-10 parts of polyacrylamide, 4-7 parts of starch and 2-5 parts of oxidase. The alloy coating material can reduce gases generated in the battery use process and prevent precipitation and layering.

Description

technical field [0001] The invention relates to the technical field of storage battery manufacturing, in particular to an alloy cladding material. Background technique [0002] A battery is a device that can convert chemical energy into electrical energy. After discharge, it can regenerate the internal active materials by charging, store electrical energy as chemical energy, and convert chemical energy into electrical energy again when it needs to be discharged. This type of battery is called It is a storage battery, also known as a secondary battery. Most of the storage batteries used in the equipment of existing automobiles and battery cars are lead storage batteries. [0003] Lead-acid batteries include positive and negative plates, both of which are composed of grid plates and active materials filled on the grid plates, and the battery is charged and discharged through the reaction of the electrolyte and the active materials. Wherein, the grid plate is braided by a plur...
