Electrolytic copper foil, as a functional basic raw material in the electronic manufacturing industry, isknown as the 'neural network' for electronic product signal and power transmission and communication. lt is mainly used for the production of printed circuit boards and lithium batteries, and the corre.sponding product categories are PCB copper foil and lithium battery copper foil.

Copper foil is a anionic electrolytic material that isdeposited in a thin, continuous layer of metal foil on thesubstrate layer of a circuit board.

Copper foil is mainly divided into electronic circuitcopper foil (used for copper clad boards and printedcircuit boards) and lithium battery copper foil (mainlyused for power lithium batteries, consumer lithium bat.teries, and energy storage lithium batteries) accordingto downstream demand.
