Carbon Coated Aluminum Foil with Excellent Corrosion Resistance

Product Description

 In the field of current collector for batteries,functional coating
is proven to be a breakthrough technology.Surface coating of Al
foil with one or more conductive materials exhibits two-dimensional
or multidimensional conductive networks.According to theoretical
simulation and experimental results,the coating technology is
optimized.Compared to state-of-the-art modified aluminum foil,the
functional coating prepared by our technology has thinner
thickness,lower resistance and enhanced adhesion.Consequently,the
electrochemical performance could be improved effectively with the
modified aluminum foil. Moreover,the cost of production and use can
be reduced.  


Application:   

 ² Lithium-ion batteries for electric vehicles and energy storage  ² Lithium-ion batteries for 3C productions  ² Super capacitor  ² Lithium-ion super capacitor  ² Cyclinder Cell  ² Soft-packing cell  ² Prismatic Cell  ² Lithium ion battery in water system  ² Alkaline batteries  


Advantage :  

 ² Improve the surface tension,and increase the adhesion between the
Al foil and the active material  ² Decrease the using amount of binder for the electrode,enhance
energy density of the battery,and lower the cost of the   electrode
production  ² Protect the Al current collector from surface corrosion and
oxidation  ² Reduce interfacial resistance and internal resistance of the cell  ² Decrease polarization and improve the rate capability and
specific capacity of the electrode material  ² Mitigate exothermal reactions and enhance the battery safety  ² Improve the production stability and reproducibility,and raise
the pass rate of the cell;Increase the consistency and   cycling
life of the cell,and lower the cost of the production
