18650 lithium-ion battery welding method, lithium-ion battery processing and welding technology. The reasonable selection of welding methods and processes in the manufacturing process of power 18650 lithium-ion batteries will directly affect the cost, quality, safety and consistency of the battery. Laser welding is used for the welding of lithium-ion batteries. Compared with traditional welding methods, the laser welding process The level is higher, the benefits are considerable, and safety issues are better solved.

We understand that the outer shell of the 18650 lithium-ion battery is a steel shell. Without a dedicated battery spot welder, it is difficult to weld with an electric soldering iron. Of course, there are also powerful battery fluxes that can be used to easily solder 18650 batteries with an ordinary soldering iron. However, this powerful flux is corrosive, not only corroding the battery casing and positive electrode, but also corroding the soldering iron tip. The welding method of 18650 lithium-ion battery is as follows:
1. First use a knife or file to scrape the area to be welded clean;
Low temperature lithium iron phosphate battery 3.2V 20A -20℃ charging, -40℃ 3C discharge capacity ≥70%
Charging temperature: -20~45℃ -Discharge temperature: -40~+55℃ -40℃ Support maximum discharge rate: 3C -40℃ 3C discharge capacity retention rate ≥70%
2. Since the material of the positive electrode is difficult to tin, it is best to grind it a little;
3. In order to prevent high temperature from damaging the 18650 lithium-ion battery, wrap the battery with a damp cloth;
4. Hold the soldering wire against the battery with one hand, and solder it with a soldering iron of sufficient temperature with the other hand to tin the positive electrode of the battery.
