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.

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.
Micro porous aluminum foil fluid collectors are widely utilized by various industries due to their diverse set of features and capabilities. Here are a few key aspects of these collectors:
1. High Porosity: Micro porous aluminum foil fluid collectors have an extremely porous structure that enables efficient fluid collection and distribution.
