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.
