Double Sides Carbon Coated Copper Foil for Battery Research

The modified copper foil is a functional layer which is coated on the surface of copper foil with a variety of conductive materials or one of them,forming a fine two dimensional or multidimensional conductive network structure, and then collocating the conductive resin suitable for water system. Double-side carbon coated copper foil well used in Battery fields for industry using as well as research.

We have Double Sides Carbon Coated Copper Foil For Battery Research as well as single side coating foil.Double Sides Carbon Coated Copper Foil widely used in market.

In conventional battery electrodes, the interface between the copper current collector and the anode coating (e.g., graphite, silicon, hard carbon) can suffer from poor adhesion, high contact resistance, and uneven current distribution. The carbon coating provides a surface-engineered layer that enhances binder anchoring and electronic pathways at the interface, helping maintain low resistance and mechanical integrity through calendaring and repeated charge–discharge cycles.

Primary research applications include:

Lithium-ion battery anodes (graphite, silicon-graphite, hard carbon)

Next-generation battery chemistries (Li-S, solid-state)

Fast-charge battery designs

High-loading electrode formulations

• Significantly reduce the increase in dynamic internal resistance of battery cells;
• Improve the consistency of pressure difference in battery packs;
• Extend the lifespan of battery packs;
• Significantly reduce battery pack costs

The application of Double Sides Carbon Coated Copper Foil can improve the peeling force of the positive and negative electrode sheets of lithium-ion batteries, thereby enhancing the battery cycle life, reducing the battery internal resistance, improving the battery's charging and discharging rate, and enhancing its charging and discharging ability in low-temperature environments. It can also improve the direct pass rate and assembly success rate in the battery production process, thereby significantly reducing the overall cost of battery manufacturing.

The Double Sides Carbon Coated Copper Foil produced by our company can be processed with high-precision coating on the thinnest 6um copper foil, and the coating surface density can be controlled between 0.02g/㎡ and 5g/㎡. That is to say, we can evenly coat a minimum of 0.02g of conductive substance on the surface of 1 square meter of copper foil, with a thickness of only 200nm. The conductive coated aluminum foil is the thinnest that can be processed with advanced coating on 10um hard high-purity aluminum foil, and the coating surface density can be controlled within 0.02g/㎡ and 5g/㎡ In other words, we can uniformly coat at least 20mg of conductive material on the surface of an aluminum foil with a thickness of only 200nm per square meter. We are currently at the forefront of this technology in the world.

The coating speed on copper foil can also reach a stable 150m/min, while the industry average speed is only 30-40m/min. At the same time, the alignment accuracy of conductive coated copper foil can still be controlled within ± 0.3mm. In terms of coating pattern design, not only can continuous full width coating be completed, but customized production can also be carried out according to customers' special requirements, which strongly supports the product design and technological progress of downstream battery enterprises. We can theoretically coat aluminum foil with any pattern, and the alignment accuracy of front and back coating can also reach ± 0.3mm, leading the entire industry.

 

 

Considerations for Research

 

When choosing a carbon coated copper foil for your research, consider the following factors:

Factor	Consideration
Substrate thickness	6-9 µm typical; thinner foils enable higher energy density cells
Coating thickness	1-2 µm per side; affects conductivity and adhesion
Coating material	Super P, KS6 graphite, or custom formulations
Width requirements	Match to your coating line or manual casting setup
Edge margin	Most products have uncoated edges (10-20 mm per side) for handling
Customization	Many suppliers offer custom coating thickness, width, and materials
