Graphene Coated Aluminum Foil Thermal Conductivity ≤0.03W/m.K

Product 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 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,

Product Features:

Ø UItra-thin coating composed of graphene.

Ø Reducing the interface resistance to improve rate capability and cycle life of L-ion battery and super capacitors.

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

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

Application:

Ø Lithium-ion batteries

Ø Super capacitors
