Description

The product is designed as a new type of aluminum foil current collector with uniform coating of graphene on its surface. Based on the excellent electrical conductivity and two-dimensional laver structure of graphene, the ultra-thin layer with a thickness of less than 0.5pm on the surface of aluminum foil has high electrical conductivity, which significantly reduces the interface resistance. and thus improves the adhesion between active materials and aluminum foil. Such a current collector is beneficial to the rate capability and cycle life of battery and supercapacitors. Its comprehensive performance is much better than those of other aluminum foils based on conventional carbon materials. it can replace traditional aluminum foil and corrosion aluminum foil for Li-ion batteries and supercapacitors.

 

Product Features:

Ultra-thin coating composed of graphene.

Reduce the interface resistance to improve rate capability and cycle life of Li-ion battery and supercapacitors.

Improving the adhesion between active materials and current collector and reducing the corrosion of current collector.

Enhancing the safety of batteries by reducing polarization and alleviating the heating up during charging

 

 

Application Areas:

Li-ion Batteries

Supercapacitors

 

Specifications & parameters:

Appearance: Dark gray coating.

Coating Thickness (double side)/um: Typically 0.5

Areal density (double side)/mg cm-2: 0.04~0.1

 

 

 

Usage Instructions

GC-foil can be directly used as current collector in Li-ion batteries or supercapacitors.

GC-foil is suitable with different coating methods. When coating, the humidity should be controlled below 30%.

When using ultrasonic welding to weld the tab on, it is suggested to set the power 10% higher than that for ordinary aluminum foil.

It is highly hygroscopic. Do not open the vacuum package before use. Once opened, it should be properly stored in a vacuum environment at room temperature after vacuum drying at 40-60C.
