Carbon-Coated Copper Foil

Negative Electrode Application Field of Lithium-ion Batteries

Carbon-coated copper foil is a crucial negative current collector material in lithium-ion batteries. The carbon coating on its surface improves the electronic conductivity, enabling smoother electron transfer during the charging and discharging process of the battery, reducing the internal resistance of the battery, and thereby enhancing the charging and discharging efficiency and power performance of the battery. It is widely used in lithium-ion battery application scenarios such as consumer electronics (such as smartphones and tablets) and electric vehicles, contributing to the improvement of the overall performance and endurance of the battery.

Flexible Electronic Device Field

With good flexibility and conductivity, carbon-coated copper foil is an ideal choice for electrode materials in flexible electronic devices. In flexible circuit boards (FPCs), wearable devices, flexible display screens, and other flexible electronic equipment, it can adapt to the deformation requirements such as bending and folding of the equipment while ensuring stable electron transfer, providing important material support for the development of flexible electronics technology and promoting the innovation and popularization of products such as wearable devices and folding screen mobile phones.

Electromagnetic Shielding and Heat Dissipation Field

Utilizing the excellent conductivity of copper and the characteristics of the carbon coating layer, carbon-coated copper foil can be used as an electromagnetic shielding material to effectively block electromagnetic interference and ensure the normal operation of electronic devices. It has important application value in environments with dense electronic equipment (such as communication base stations and data centers). In addition, its good thermal conductivity also enables it to play a role in the heat dissipation field. It can be used as part of a heat sink or thermal management material to help electronic devices dissipate the heat generated during operation, improving the stability and service life of the equipment.
