Carbon-Coated Etched

Lithium-ion Battery Field

In lithium-ion batteries, carbon-coated and etched aluminum foil is mainly used as the positive current collector. The carbon coating on its surface can improve electronic conductivity, reduce the internal resistance of the battery, and enhance the charge-discharge performance of the battery, enabling the battery to charge and discharge quickly. It is suitable for high-power application scenarios, such as the power systems of electric vehicles and electric tools, helping to improve the efficiency and performance of the equipment.

Supercapacitor Field

As the electrode material of supercapacitors, the high specific surface area and good conductivity of carbon-coated and etched aluminum foil contribute to increasing the energy storage density and power density of supercapacitors. It plays a crucial role in systems that require rapid energy storage and release, such as energy buffering in renewable energy systems and instantaneous power compensation in industrial equipment, ensuring the stable operation of the systems.

Other Energy Storage and Electronic Device Fields

With its unique performance advantages, it can be applied in other emerging energy storage technologies or special electronic devices. For example, in some new hybrid energy storage systems, it works in cooperation with other energy storage materials to optimize the overall energy storage performance; in electronic devices with high requirements for electrode material conductivity and stability, such as high-performance sensors and flexible electronic devices, it provides reliable electrode support, expanding the functions and application range of electronic devices.
