Lishui optimal heat dissipation copper foil processing
The commonly used reinforcement materials of copper clad laminate are alkali free (alkali metal oxide content shall not exceed 0.5%) glass fiber products (such as glass cloth, glass felt) or paper (such as wood pulp paper, bleached wood pulp paper, cotton wool paper). Therefore, laminates can be divided into glass cloth base and paper base.

High end lithium battery copper foil needs to meet the requirements of high energy density, high safety, lightweight and other characteristics of power batteries, which is also the development trend of power batteries in the future. In order to meet the above characteristics, thinner lithium copper foil means smaller resistance, so the energy density and other performance of the battery will be improved. Moreover, the thinner the copper foil of lithium battery is, the lighter the weight of the corresponding battery will be.

Copper foil is not a traditional metal copper product. It combines design concepts such as composite material and nano material technology, and different internal microstructures, resulting in different properties from traditional pure copper. The application of copper foil mainly focuses on the characteristics of conduction, heat conduction and electromagnetic wave shielding.

The foil of the clad plate can be copper, nickel, aluminum and other metal foils. However, considering such factors as the conductivity, solderability, elongation, adhesion to the substrate and price of gold, it is considered appropriate except for special purposes.
