NOVELTY - Preparing a metal porphyrin TPyP(M2+)/rGO composite structure, comprises self-assembling pyridyl porphyrin molecules by solution method to obtain metal porphyrin TPyP (M2+) and then self-assembling to form metal porphyrin in an acetic acid solution, combining with rGO pi-pi, stirring and reacting for a period of time in an ice bath environment, and then centrifugally drying to obtain the final product. USE - The composite structure is useful as lithium-ion anode material (claimed) in lithium-ion battery and electrochemical energy storage field. ADVANTAGE - The structure: is convenient for fast transmission of electron; has ultra-high theoretical specific capacity, discharge voltage and power density; ensure the excellent cycle stability and energy density of battery; and the method is simple and easy; and reduces the accumulation of metal porphyrin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a use method of metal porphyrin TPyP(M2+)/rGO composite structure.
