▎ 摘　　要

NOVELTY - Sulfurized porphyrin-based covalent triazine composite anode material is claimed. The anode material is prepared by (i) reacting bispyrrole and p-cyanobenzaldehyde under the protection of an inert gas to obtain a porphyrin-based monomer, (ii) combining the porphyrin-based monomer obtained in step (i) with metal element to obtain metalloporphyrin complex, (iii) reacting the metalloporphyrin complex obtained in step (ii) with zinc chloride to obtain covalent triazine polymer, (iv) sintering the covalent triazine polymer obtained in step (iii) with sublimed sulfur to obtain sulfurized porphyrin-based covalent triazine material, and (v) mixing the sulfurized porphyrin-based covalent triazine material obtained in step (iv) with sulfide solid electrolyte and conductive carbon for ball-milling to obtain the sulfurized porphyrin-based covalent triazine composite anode material. USE - The sulfurized porphyrin-based covalent triazine composite anode material is useful in an all-solid-state battery (claimed); and in high-performance organic electrode materials. ADVANTAGE - The method provides porphyrin-based covalent triazine framework material having high specific surface area; when used as anode material for lithium-ion batteries, it has high capacity and excellent rate performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for all-solid-state battery, comprising the sulfurized porphyrin-based covalent triazine composite anode material.
