Battery welding copper tape functions as a low-resistance conductor between individual battery cells, creating series or parallel connections within a battery pack. The 99.97% pure copper composition ensures maximum electrical conductivity, minimizing energy loss as heat during charge/discharge cycles. The tape's specific thickness (0.1-0.3mm) and hardness (1/2H) balance flexibility for assembly with structural integrity to maintain connections under vibration. During welding (typically laser or ultrasonic), the pure copper material creates strong, low-resistance bonds with battery terminals, forming efficient electrical pathways that enable safe and reliable power distribution throughout the battery pack.
