Lithium battery tab connection method

Lithium battery tab connection method 1. Use screws after drilling and tapping. Advantages: high mechanical connection strength, firmness and low cost. Disadvantages: The thickness is unknown and there is a certain risk. 2. After drilling and tapping, use common solder to solder the copper wire and test with an aluminum block. Process flow: punching steel wire. Advantages: simple equipment, convenient operation and low cost. Defects: The reliability of welding needs to be tested. 3. Direct welding with M51 welding wire (low-temperature welding wire), welding data: M51+M51-f, low-temperature copper-aluminum welding. The abbreviation of M51WEWELDINGM51, also known as General 51 years old, is the processor logo of the company's research and development industry. This is a particularly rare element containing low-temperature copper-aluminum welding wire. It was introduced to my country by Wei Oding (Tianjin) Co., Ltd. in 2010. The mainland's first technology for low temperature welding is important in almost all white metals, white alloys contain zinc (almost no welding), aluminum alloys, copper, lead, tin-lead alloys and lead. M51 can also weld any of these metals to other metals, such as copper, brass, steel, stainless steel or bronze. The price is a bit expensive, the diameter is 1.3mm, the length is 3 meters, M5125 yuan, and the small bottle M51-fflux is 50 yuan. Advantages: The analysis says that the equipment is simple and the weldability is strong. Disadvantages: the cost is high. Whether it is sturdy or not is to be tested.
