Carbon Coated Cu Foils For Lithium Ion Battery

Carbon Coated Cu Copper Foils

Product Description

 Surface modification of battery collector using functional coatings
is a breakthrough technological innovation.The modified copper foil
is a functional layer which is coated on the surface of copper foil
with a variety of conductive materials or one of them,forming a
fine two-dimensional or multidimensional conductive network
structure,and then collocating the conductive resin suitable for
water system. Through the combination of theoretical simulation
calculation and many experiments,the optimal ratio structure and
process strip are found out.Piece.The process can make the coating
thickness thinner,the coating resistance lower and the adhesion
ability stronger,in order to effectively improve the
electrochemical performance and product stability of lithium
battery,especially for silicon carbon battery system.  


Product Features  

 Ø Improve the surface tension,and increase the adhesion between the
Cu foil and the active material  Ø Reduce the amount of binder in the electrode,increase the energy
density and cycle life of the battery.  Ø Protect the Cu current collector from surface corrosions and
oxidations  Ø Reduce interface resistance and reduce battery internal
resistance  Ø Decrease polarization and improve the rate capability and
specific capacity of the electrode material  Ø Mitigate exothermal reactions and enhance the battery safety  Ø lmprove 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  
Application:   

 Ø Lithium-ion batteries for electric vehicles and energy storage  Ø Lithium-ion batteries for 3C productions  Ø Lithium ion battery in water system  


Usage and storage:   

 Ø Use the product in the workshop with humidity of ≤20%RH and a
high dust purification.  Ø Store the product below 35℃, do not open the vacuum package
before use .after use ,the left product should be dried at 40-60℃
for 2   hours under vacuum ,then kept in the cabinet filled with
nitrogen at room temperature.  Ø The product can be stored under vacuum package for one year at
ambient temperature and moisture without direct sun. Once the  
vacuum package is opened, the product can be kept under vacuum
cabinet for at most one month
