It is mainly used for electromagnetic shielding and antistatic. The conductive copper foil is placed on the substrate surface and combined with metal substrate, which has excellent conductivity and provides electromagnetic shielding effect. It is widely used in industrial calculators, communication equipment, QA equipment, lithium-ion batteries, civil TV sets, video recorders, CD players, copiers, telephones, cold and warm air conditioning, automotive electronic components, game machines, etc. Performance advantages

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

2. Improve the adhesion between active material and collector, and reduce the manufacturing cost.

3. Reduce the polarization, improve the rate and capacity, and improve the performance of the battery.

4. Protect the collector and prolong the service life of battery.
