Pack Manufacturer <\/div>\n<\/div>\n<p> The customer is a leading German manufacturer focused on large-scale cylindrical battery module (21700) production. Previously used pure-nickel busbars produced excessive pack resistance and cell temperature rise during 3C discharge. Inconsistent pad dimensions from different suppliers also caused incomplete laser welds. The customer sought lower internal resistance and more consistent welding without changing the production line. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><\/data-content><\/p>\n<\/div>\n<div class=\"dc-content-bg\">\n<div class=\"dc-content\">\n<h2 class=\"dc-about-h2\"> Case Overview <\/h2>\n<p> Jiangsu DZX supplied a German cylindrical battery pack (21700) manufacturer with a customized <strong> copper-nickel composite busbar <\/strong> solution. A metallurgically bonded copper-core\/nickel-surface structure replaced pure-nickel busbars, significantly improving pack connection resistance and temperature rise during 3C discharge. Pads were stamped for the cell specifications to \u00b10.05mm tolerance, reducing laser-welding defects to nearly zero.
