Graphene Coated Aluminum Foil
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 and two-dimensional layer structure of ultra-thin layer with a thickness of less than 0.5μm 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 comprehensive performance 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.
● UItra-thin coating composed of graphene.
● Reducing the interface resistance to improve rate capability and cycle life of L-ion battery and super capacitors.
● 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.
● Lithium-ion batteries
● Super capacitors
