Copper foil has low surface oxygen characteristics and can adhere to a variety of different substrates, such as metals and insulating materials, with a wide temperature range of use. It is mainly used for electromagnetic shielding and anti-static purposes. When conductive copper foil is placed on the substrate surface and combined with metal substrates, it has excellent conductivity and provides electromagnetic shielding effects. It can be divided into: self-adhesive copper foil, double-conductor copper foil, single-conductor copper foil, etc. Electronic-grade copper foil (purity above 99.7%, thickness 5um-105um) is one of the basic materials of the electronics industry. With the rapid development of the electronic information industry, the usage of electronic-grade copper foil is increasing, and products are widely used in industrial calculators, communication equipment, QA equipment, lithium-ion batteries, consumer televisions, VCRs, CD players, copiers, telephones, heating and cooling air conditioners, automotive electronic components, game consoles, and more. The domestic and international markets for electronic-grade copper foil, especially high-performance electronic-grade copper foil, are increasing. Relevant professional agencies predict that by 2015, China’s domestic demand for electronic-grade copper foil will reach 300,000 tons, and China will become the largest manufacturing base for printed circuit boards and copper foil in the world, with a promising market outlook for electronic-grade copper foil, especially high-performance foil.
Performance Advantages of Carbon-Coated Copper Foil
1. Significantly improve the consistency of battery pack usage and greatly reduce the cost of battery packs.
· Significantly reduce the increase of the cell's dynamic internal resistance; · Improve the consistency of the battery pack's voltage difference; · Extend the battery pack's lifespan;
2. Improve the bonding adhesion of active materials and current collectors, reducing electrode sheet manufacturing costs. For example:
· Improve the adhesion of cathode materials and current collectors using aqueous systems; · Improve the adhesion of nanoscale or submicron-scale cathode materials and current collectors; · Improve the adhesion of lithium titanate or other high-capacity anode materials and current collectors;
· Increase the qualified rate of electrode sheets and reduce manufacturing costs.

After using carbon-coated aluminum foil, the adhesion strength of the electrode sheets increases from the original 10gf to 60gf (using tape or the hundred-grid knife method), significantly enhancing adhesion.
3. Reduce polarization, increase the rate and specific capacity, and improve battery performance. For example:
· Partially reduce the proportion of binder in the active material to increase capacity; · Improve the electrical contact between the active material and the current collector; · Reduce polarization and improve power performance.
