摘要： Disclosed are a method of manufacturing a composite anode for a lithium ion battery and a composite anode for a lithium ion battery manufactured thereby. According to the method provide herein, since a metal catalyst precursor is reduced using Joule heating to obtain a carbon-metal catalyst composite layer, composite anode for a lithium ion battery having a large area in a short period of time can be provided, which is excellent in terms of economic feasibility. Further, since it is possible to manufacture a composite anode for a lithium ion battery with the improved lithium electrodeposition density and reversibility of lithium ions, a composite anode for a lithium ion battery having high capacity and improved life stability can be obtained.
