摘要：NOVELTY - A silicon/polyacrylonitrile composite cathode pole comprises 80-90 %mass silicon, 10-20 %mass polyacrylonitrile and N-methylpyrrolidone used as solvent. The composite cathode pole is prepared by drying and coating the coating film. USE - Silicon/polyacrylonitrile composite cathode pole for lithium ion battery. ADVANTAGE - The composite cathode pole improves the volume expansion effect of silicon, and is prepared by simple process at low cost with excellent electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation silicon/polyacrylonitrile composite cathode pole, which involves taking silicon powder and polyacrylonitrile, adding appropriate amount of N-methylpyrrolidone, magnetically-stirring for 8 hours, evenly mixing, taking out homogeneous mixed slurry, coating with a coating machine on a copper foil, and drying in oven at 80 degrees C for 12 hours.
