NOVELTY - Producing cathode material, comprises (i) dissolving graphene oxide into water to form graphene oxide slurry, (ii) adding aniline monomer into graphene oxide slurry to form first mixed slurry, (iii) adding phytic acid into first mixed slurry to form second mixed slurry, (iv) adding silicon nanoparticles into second mixed slurry to form third mixed slurry, (v) adding initiator into third mixed slurry to form fourth mixed slurry, and (vi) directly coating and drying fourth mixed slurry to form cathode material of silicon-based lithium ion battery. In the step (i), benzene ring structure on aniline monomer forms pi - pi bond with graphene oxide. In the step (ii), benzene ring and aniline monomer on phytic acid are mutually attracted and connected. In the step (iii), silicon nanoparticles are chelated with phosphate groups on phytic acid to closely bond aniline monomers to silicon nanoparticles. USE - The cathodematerial is useful for silicon-based lithium ion battery (claimed). ADVANTAGE - The cathodematerial is simple to produce and economical. The method improves productivity. DETAILED DESCRIPTION - Producing cathode material, comprises (i) dissolving graphene oxide into water to form graphene oxide slurry, (ii) adding aniline monomer into graphene oxide slurry to form first mixed slurry, (iii) adding phytic acid into first mixed slurry to form second mixed slurry, (iv) adding silicon nanoparticles into second mixed slurry to form third mixed slurry, (v) adding initiator into third mixed slurry to form fourth mixed slurry, and (vi) directly coating and drying fourth mixed slurry to form cathode material of silicon-based lithium ion battery. In the step (i), benzene ring structure on aniline monomer forms pi - pi bond with graphene oxide. In the step (ii), benzene ring and aniline monomer on phytic acid are mutually attracted and connected. In the step (iii), silicon nanoparticles are chelated with phosphate groups on phytic acid to closely bond aniline monomers to silicon nanoparticles. In the step (v), aniline monomer is polymerized in situ under initiation of initiator to form polyaniline, and graphene oxide is pulled to encapsulate polyaniline. An INDEPENDENT CLAIM is also included for silicon-based lithium ion battery anode material obtained by the above method, and comprising polyaniline skeleton pore-type microstructure which is attached to the graphene oxide-coated silicon nanoparticle.
