Red copper foil

Copper foil has low surface oxygen characteristics, can be attached to a variety of different substrates, such as metal, insulation materials, etc., with a wide temperature range. Mainly used in electromagnetic shielding and antistatic, the conductive copper foil is placed on the substrate surface, combined with the metal substrate, has excellent conductivity, and provides the effect of electromagnetic shielding. Can be divided into: self-adhesive copper foil, double guide copper foil, single guide copper foil and so on. Electronic grade copper foil (purity above 99.7%, thickness 5um-105um) is one of the basic materials of the electronic industry, the rapid development of the electronic information industry, the use of electronic grade copper foil is increasing, products are widely used in industrial calculators, communication equipment, QA equipment, lithium ion batteries, Civilian TV, video recorder, CD player, photocopier, telephone, heating and cooling air conditioning, automotive electronic parts, game consoles, etc.

Performance advantages of carbon-coated copper foil

1. Significantly improve the consistency of battery pack use and greatly reduce the cost of battery pack.

· Significantly reduce the increase of dynamic internal resistance of the cell;

· Improve the differential pressure consistency of the battery pack;

· Extend battery life.

2. Improve the adhesion of the active material and the collector, and reduce the manufacturing cost of the pole sheet. Such as:

· Improve the adhesion of cathode materials and collectors using water-based systems;

· Improve the adhesion of cathode materials and collector at the nanoscale or submicron scale;

· Improve the adhesion of lithium titanate or other high-capacity negative electrode materials and collectors;

· Improve the qualified rate of electrode sheet and reduce the manufacturing cost of electrode sheet.

3. Reduce polarization, improve magnification and gram capacity, and improve battery performance. Such as:

· Partially reduce the proportion of adhesive in the active material and increase the gram capacity;

· Improve the electrical contact between the active substance and the collector;

· Reduce polarization and improve power performance.

4. Protect the fluid collection and extend the battery life. Such as:

· Prevent collector corrosion and oxidation;

· Improve the surface tension of the collector, and enhance the coating performance of the collector;

· Can replace higher-cost etched foil or replace standard foil with thinner foil
