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.
