Embodiment 1

[0029] Lead powder manufacturing process:

[0030] After the electrolytic lead is crushed, it is placed in a pulverizer to make lead powder, and then the lead powder is oxidized. After the lead powder is oxidized, it is placed in the powder storage bin for 2.5 days of aging treatment before use.

[0031] Partition manufacturing process:

[0032] Mix glass fiber, expandable microcapsule polyacrylonitrile resin, and cationic polyacrylamide according to the mass ratio of 88:11:1, add water to make a colloid solution, and then dry the colloid solution to make a separator. The average glass fiber used The diameter is 1.1um.

[0033] Grid casting process:

[0034] a1: Weigh the lead, aluminum and aluminum-calcium alloy according to the mass ratio of 99.35:0.5:0.15 and put them into the melting furnace for melting at 680°C, wherein the mass ratio of aluminum and calcium elements in the aluminum-calcium alloy is 1:1.5, After smelting, add slag cleaning agent to remove scum while st...

Embodiment 2

[0046] Lead powder manufacturing process:

[0047] After the electrolytic lead is crushed, it is placed in a pulverizer to make lead powder, and then the lead powder is oxidized. After the lead powder is oxidized, it is placed in a powder storage bin and left to stand for aging treatment for 2 days before use.

[0048] Partition manufacturing process:

[0049] Mix glass fiber, expandable microcapsule polyacrylonitrile resin, and cationic polyacrylamide according to the mass ratio of 85:14:1, add water to make a colloid solution, and then dry the colloid solution to make a separator. The average glass fiber used The diameter is 1.0um.

[0050] Grid casting process:

[0051] a1: Weigh the lead, aluminum and aluminum-calcium alloy according to the mass ratio of 99.35:0.5:0.15 and put them into the melting furnace for melting at 680°C, wherein the mass ratio of aluminum and calcium elements in the aluminum-calcium alloy is 1:1.5, After smelting, add slag cleaning agent to remov...

Embodiment 3

[0063] Lead powder manufacturing process:

[0064] After the electrolytic lead is crushed, it is placed in a pulverizer to make lead powder, and then the lead powder is oxidized. After the lead powder is oxidized, it is placed in a powder storage bin and left to stand for aging treatment for 3 days before use.

[0065] Partition manufacturing process:

[0066] Mix glass fiber, expandable microcapsule polyacrylonitrile resin, and cationic polyacrylamide according to the mass ratio of 90:9:1, add water to make a colloid solution, and then dry the colloid solution to make a separator. The average glass fiber used The diameter is 1.2um.

[0067] Grid casting process:

[0068] a1: Weigh lead, aluminum and aluminum-calcium alloy according to the mass ratio of 99.35:0.5:0.15 and put them into the melting furnace for melting at 680°C, wherein the mass ratio of aluminum and calcium elements in the aluminum-calcium alloy is 1:1.5, After smelting, add slag cleaning agent to remove scu...

Abstract

The invention discloses a production process of a storage battery. The production process specifically comprises the following procedures: manufacturing lead powder, casting a plate grid, manufacturing a partition, manufacturing a polar plate, forming the polar plate and assembling the battery. According to the production process, in the partition manufacturing procedure, the partition which is manufactured by mixing glass fiber, expandable micro-capsule polyacrylonitrile resin and cationic polyacrylamide is utilized, the liquid gasification speed of the prepared and obtained storage battery is low, the loss of an electrolyte of the storage battery can be effectively reduced, and the service life of the storage battery can be prolonged.

Description

technical field [0001] The invention relates to the field of battery production, in particular to a production process of a storage battery. Background technique [0002] At present, the commonly used batteries mainly fall into the following three categories: [0003] Ordinary battery; the plate of ordinary battery is composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid; its main advantages are stable voltage and low price; the disadvantage is low specific energy (that is, the electric energy stored per kilogram of battery) , short service life and frequent routine maintenance. [0004] Dry-charged battery: the full name is dry-type charged lead-acid battery. Its main feature is that the negative plate has a high power storage capacity. In a completely dry state, it can save the obtained power within two years. When using it, just add Electrolyte, wait 20 to 30 minutes before use. [0005] Maintenance-free battery: Due to its own s...
