The present invention relates to a method for manufacturing a graphene-based composite anode material, and a cathode material and a lithium ion battery produced thereby. Specifically, the method comprises the steps of: (1) mixing the graphite raw material and graphite oxide uniformly and obtaining a mixture; (2) adding a binder to the mixture and kneading to obtain a kneaded product; Step (3), rolling the kneaded material to obtain a knitted fabric; (4) a step of grinding the knitted fabric to obtain a powder material; Step (5), performing compression molding on the powder material to obtain a compression molded article; Step (6) includes the step of performing graphitization treatment on the compression-molded article in a protective atmosphere to obtain a graphene-based composite anode material. The negative electrode material manufactured according to the above method has a stable structure, high capacity, conductivity, speed-rate performance, excellent liquid-absorbing performance and circulating performance, and can satisfy various demands in application.
