▎ 摘　　要

NOVELTY - Preparing a graphene/manganese dioxide nano-sheet array material, comprises (i) preparing a manganese dioxide nano sheet array, and (ii) taking the manganese dioxide nano sheet array as a first substrate, and performing in situ in the reaction solution, where the reaction solution includes hexaacetylenylbenzene, cuprous iodide, tetramethylethylenediamine and tetrahydrofuran. USE - The array material is useful for zinc ion anode material (claimed). ADVANTAGE - The method is mild, simple and is suitable for large-scale preparation. The zinc ion anode material has improved specific capacity, rate performance and cycle performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) graphene/manganese dioxide nano-sheet array material obtained by the method as mentioned above; and (2) zinc ion secondary battery comprising a anode, where the anode is formed of the graphene/manganese dioxide nanosheet array material.
