Main uses of copper foil

The main uses of copper foil:

The first one is that copper foil can very well improve the consistency of the use of the battery pack, thus fundamentally being able to greatly improve the composition of the battery. Cost reduction.

The second is that it can greatly improve the bonding force between the active material and the current collector, thereby greatly reducing the corresponding cost of manufacturing the pole piece.

The third is that copper foil can effectively reduce polarization, thereby improving the corresponding parameters related to rate and gram capacity, which greatly improves the performance of related batteries.

Introduction:

Copper foil is a cathodic electrolytic material. It is a thin, continuous metal foil deposited on the base layer of the circuit board. It serves as the conductor of the PCB. body. It easily adheres to the insulating layer, accepts the printed protective layer, and forms circuit patterns after corrosion.

Copper foil is made of copper plus a certain proportion of other metals. There are generally two types of copper foil: 90 foil and 88 foil, that is, the copper content is 90 and 88, and the size is 16*16cm copper Foil is the most versatile decorative material. Such as: hotels, temples, Buddha statues, gold-lettered signs, tile mosaics, handicrafts, etc.

Copper foil has low surface oxygen characteristics, can be attached to various substrates, such as metals, insulating materials, etc., and has a wide temperature range. It is mainly used for electromagnetic shielding and anti-static. The conductive copper foil is placed on the substrate surface and combined with the metal substrate to have excellent conductivity and provide electromagnetic shielding effect.
