Lithium-ion battery tab connection method

Lithium-ion battery tab connection method 1. After drilling and tapping, screw on. Advantages: analytically speaking, the equipment is simple and the welding is firm. Disadvantages: the cost is high. M51 is the abbreviation of WEWELDING-M51. M51 can also weld any of the above metals with copper, brass, steel, stainless steel or bronze and other metals. , Search Ma Yun’s home, a small bottle of M51-F flux costs 50 yuan, solid and reliable, white metals including zinc (almost impossible to solder), copper-lead alloy, tin-lead alloy, aluminum and lead, etc., the cost is low, the United States RD The brand manufactured by the industrial company, advantages: high mechanical connection strength, disadvantages: due to unknown thickness, easy to operate, there is a certain risk, in 2010 by the Welding (Tianjin) Welding Technology Co., Ltd. introduced the mainland of China, which is mainly used to solve the problem at low temperature. Significant capabilities of all white metals. Advantages: simple equipment, low-temperature copper-aluminum welding. It is a low-temperature copper-aluminum welding wire containing special rare elements. M51 with a diameter of 1.3 mm and a length of 3 meters costs 25 yuan, the price is a bit expensive, disadvantages ：Whether the welding is firm or not needs to be tested, also called Wanneng 51. Steps: Punch the hole and fill the hole with tin welding wire. Don’t forget to plug the copper wire. The copper wire 1.0 soldering iron vise can’t pull down the copper wire. It’s a pole for safety. It takes two to three holes and then the copper strip is quite strong. Use aluminum block to test, low cost, welding material: M51+M51-F, 3. Use M51 welding wire (low temperature welding wire) for direct welding, 2. Use after drilling and tapping Ordinary solder welding copper wire, whether it is firm or not needs to be tested.
