N2 Copper-Nickel Composite Tape And T2 Composite Cell Have Good Weldability
Product Description
Copper-nickel composite tape. The pure mechanical composite manufacturing method is adopted, and the copper and nickel composite interface molecules are infiltrated and fused into one through a special process without adding any medium, and a nickel-copper composite material with strong bonding force is manufactured. The copper-nickel composite tape has been greatly improved for reducing the internal resistance of the battery and prolonging the service life of the battery. As a negative electrode material, the nickel surface is the welding surface, and the copper surface is the conductive surface, which combines the advantages of nickel-plated copper strip and nickel strip, and makes the performance of the negative electrode material better.
The products produced by the company are nickel-copper composite strips, nickel-aluminum composite strips, nickel-plated copper strips, copper-aluminum composite strips, zinc-copper composite strips, pure nickel strips, nickel-plated steel strips, aluminum strips, pure nickel connecting sheets, etc. Domestic and foreign battery companies.
Performance
The nickel-copper composite tape produced uses the weldability of nickel and the excellent electrical conductivity of copper to reduce the internal resistance of the entire battery, which not only prolongs the discharge time of the battery, improves the service life of the battery, but also saves costs.
Features
(1) Excellent heat dissipation characteristics, significantly reducing the internal resistance of the battery by more than 10%, thereby greatly improving the safety of lithium batteries;
(2) The product has excellent electrical conductivity, and the electrical conductivity is 57% IACS, which is 2.5 times that of pure nickel;
(3) Excellent mechanical properties, which can be designed and adjusted according to customer requirements;
(4) CN-2 is a double-layer composite; NCN-2 is a three-layer composite, with copper in the middle and nickel on both sides;
(5) CN-2 has a certain anti-oxidation ability after surface passivation; both sides of NCN-2 are nickel, which has strong anti-corrosion ability.
