▎ 摘  要

NOVELTY - Graphene oxide-doped porous coordination polymer anode material comprises graphene oxide and porous coordination polymer Cu-MOF (copper-metal organic framework) doped in graphene oxide. The introduction of the graphene oxide provides a hierarchical structure of a three-dimensional grid. The porous coordination polymer Cu-MOF is compounded with graphene oxide by a stirring method at room temperature. The porous coordination polymer Cu-MOF achieves morphology control under the control of the ratio of polyvinylpyrrolidone, showing the mutual transformation of cubes and spheres. USE - Graphene oxide-doped porous coordination polymer anode material is useful for high-performance lithium-ion batteries. ADVANTAGE - The material realizes transformation of cube and sphere, as each physical property test and electrochemical electrode, battery performance and soon test; has excellent conductivity finally obtains lithium-ion battery cathode material with high stability; improves the charging and discharging efficiency of cathode and improves cycle performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene oxide doped porous coordination polymer, comprising (i) adding copper (II) nitrate hexahydrate and aqueous polyvinylpyrrolidone to the graphene oxide suspension, stirring and mixing uniformly; (ii) dissolving trimesic acid in the triethylamine solution, filtering the triethylamine salt obtained by distillation under reduced pressure, and mixing uniformly with the solution; (iii) stirring the mixed solution at room temperature, centrifuging the obtained precipitate, and washing with ethanol to obtain a solid precipitate; and (iv) vacuuming, and freeze-drying the solid precipitate in a freeze dryer.
