Micro Porous Copper Foil Collector is carbon coated copper foil. 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.
