Carbon-Coated Copper Foil for Advanced Lithium Battery Research

Product Details

Carbon-coated copper foil plays a crucial role in lithium battery research, especially in improving the performance and efficiency of lithium-ion batteries. The carbon coating on the copper foil serves several essential functions:

Conductive Surface:The carbon coating provides a highly conductive surface for the lithium ions to move between the anode and cathode, improving the overall conductivity of the battery.

Stabilizing the Electrode: The carbon coating helps stabilize the electrode structure, reducing the volume changes that occur during charge and discharge cycles. This stabilization enhances the battery's cycling stability and overall lifespan.

Enhancing Adhesion: The carbon coating improves the adhesion between the copper foil and the active materials, ensuring better contact and facilitating efficient electron transfer.

Preventing Dendrite Formation: The carbon coating can help prevent the formation of lithium dendrites, which can cause short circuits and compromise the safety of the battery.

Improved Energy Density: By enhancing the overall performance and stability of the battery, the carbon-coated copper foil contributes to improved energy density and efficiency of lithium-ion batteries, making them more suitable for various applications, including electric vehicles and portable electronics.

Note: The copper foil surface can be coated by carbon, cathode materials, e.g. LiFePO4, LiCoO2, upon request.
