METHOD FOR MANUFACTURING SIO-BASED CARBON NANOFIBER COMPOSITE ON BASIS OF NICKEL-COPPER CATALYST USING ELECTROPHORETIC DEPOSITION, AND METHOD FOR MANUFACTURING SECONDARY BATTERY USING SAME

摘要

The present invention relates to a method for manufacturing SiO-based carbon nanofiber composite on the basis of a nickel/copper catalyst using electrophoretic deposition and a method for manufacturing a secondary battery using the same as an anode material, said method for manufacturing SiO-based carbon nanofiber on the basis of nickel/copper catalyst using electrophoretic deposition comprising the steps of: (a) depositing a nickel and copper catalyst on carbon fiber fabric by electrophoretic deposition using a carbon electrode as an anode and the carbon fiber fabric as a cathode; (b) reducing the carbon fiber fabric on which the nickel and copper catalyst is deposited; (c) growing carbon nanofiber on the reduced carbon fiber fabric by chemical vapor deposition using an ethylene gas; and (d) coating SiO2 on the grown carbon nanofiber fiber. As such, the present invention provides a method for simply manufacturing an anode material of a lithium secondary battery having good electrochemical properties, and a method for manufacturing a lithium secondary battery having high charging and discharging efficiency, great capacity, and long lifetime by using said manufactured anode material.
