Conventional battery internal connecting sheet material include nickel belts and copper strips. The advantages of the pure nickel belt: good welding performance, strong antioxidant capacity, disadvantage: the internal resistance is large; the advantages of nickel-plated copper strips: small resistance, disadvantage: the welding performance of the thin coating is generally, it is easy to fall off.

The battery can be connected with a copper sheet. The conductivity of copper is definitely better than nickel (in all metal materials, copper conductivity is second only to silver, but copper has a disadvantage - easy to oxidize in air. In fact, the so-called "nickel sheet" you see is just a nickel plated bronze tablets, and nickel plating is to prevent copper oxidation. Pure nickel having roll and sheet shapes, is applied as the connecting bar, terminal lug, lead-out bar, and current collector on battery production and combination. There are also local golded, tinned and other high-tech communication product accessories.

Our company can stamp and cut according to customer drawings design. Gingerm usually uses the nickel strip with 0.15 mm thick pure nickel. The nickel belt surface can be embossed stripe. After progressive stamping production, ultrasonic cleaning is required. Our monthly delivery 50,000 according to customer procurement needs, often prepared in stock, timely delivery. We warmly welcome the battery industry to call and conduct technical advice and inquiry.
