Welding Battery Terminals. Battery terminal and tab are welded by series welding method. Overheating the battery are important aspects of tab to terminal welding.
Anode cathode terminal In addition to the housing typical laser applications for prismatic Li-ion batteries include welding of the anode cathode terminal in a single cell. Spot welding was conducted between Hilumin connecting strips and both of positive and negative terminals of SAMSUNG INR18650-15L Li-ion battery. Each of these welding techniques has its own characteristics depending on the material properties and contact geometry.
Will you be joining internal terminal connections performing battery can and fill plug sealing making tab to terminal connections or welding external electrical connections.
The materials material thickness and combination of materials determine the best welding technique. As mentioned above the most popular battery spot welder package consists of theCD400DP and the WH2125. Internal terminal connections battery can and fill plug sealing tab to terminal connections and external electrical connections are a few key examples. Here the positive terminal is made of aluminum and the negative terminal is made of copper.
