18650 lithium ion battery welding method, 18650 battery point cap steps. The outer casing material of the 18650 lithium-ion battery is a common galvanized steel cylinder. It is very convenient to use iron iron to give it tin.

It is very convenient to use the spot welder to weld it. 18650 lithium-ion battery welding on the relevant experience or skills of the operator is still more, because it requires us to follow the appropriate step method as much as possible. 18650 lithium-ion battery welding method for lovers, sometimes use electric soldering iron welding 18650 lithium-ion batteries, many people will say that the electric soldering iron welding 18650 battery is not safe, not strong, etc.

It is very disadvantageous to buy a battery in order to weld a battery. The general people welding 18650 lithium-ion battery operation is like this: take a block cloth or sharp thing, grind the two levels of the battery, so that its two-stage nickel-plated crust becomes rough, so that it is more convenient to weld the tin. .

It is certain that this is a very good way, but there is also its shortcomings, that is, not strong, easy to fall off. Under normal circumstances, the iron soldering is very poor. Because the 18650 lithium-ion battery of the regular manufacturer is used in stainless steel housing, the adhesive effect is very poor.

General welding 18650 is a spot welder. Generally 18650 lithium-ion battery welding method is as follows: 1. First, use a knife or file to apply the water welded portion to weld the soldering site.

2. Because the material of the positive is more difficult, it is best to grind the flowers; 3. In order to prevent high temperature from destroying the battery, Pack the battery with a wet cloth; 4.

One hand with solder wire to 18650 lithium-ion battery, one hand is welded with sufficient temperature solder iron, for the battery positive tin. 18650 Battery point cap Step 1, well equipped Labor insurance supplies, temperature and humidity requirements, temperature: 15 ~ 26 ° C, glove box dew point temperature ≤ -35 ​​° C, sealing room ≤ -30 ° C; 2, after the liquid, the lithium ion battery electrolyte is complete, the electrolyte does not The over-way process is returned after confirming the quality personnel. 3.

Adjust the laser welder as spot welding mode and set parameters such as point soldering current, pulse width. 4,18650 After the battery spot welded, the aluminum washed into the "V" font, and then pressed the cap in the battery roller step. After the cap is pressed, it is contacted to the material box and transferred to the seal.

Step; After the operation is completed, turn off the laser welder power, clean, clean the site, after the corresponding grouping in 18650, by design can be made into 11.1V lithium ion battery pack and can be used on various related electronic digital products. If the battery cap does not weld, it cannot be used to make a battery pack.

The above is the 18650 lithium-ion battery welding method, 18650 battery point cap steps. The outer casing of the 18650 lithium-ion battery is a stainless steel shell. When using a mixed metal welding, it is very convenient to use a spot welder.

In the case of amateur, there is no spot welder.
