▎ 摘　　要

NOVELTY - Laminated structure composite of graphene with low defect concentration comprises a compound composed of a low-defect concentration graphene active substance FeXa, where X is oxygen, sulfur, selenium, nitrogen, carbon, and/or phosphorus and a = 0-3, the composite is that the defect concentration on the surface of graphene is maintained at the level of pristine graphite, and FeXais sandwiched between graphene layers with consistent orientation heights. USE - Laminated structure composite of graphene with low defect concentration for preparation of electrode material of alkali metal ion battery in electrochemical field. ADVANTAGE - The laminated structure composite has low defect concentration and high conductive state of graphite and graphene. The alkali metal ion battery has high first cycle coulomb efficiency, high specific capacity, and excellent rate performance. The method has mild condition and strong commonality. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing laminated structure composite of graphene with low defect concentration comprising adding iron trichloride graphite intercalation compound (iron chloride) to an amine solution and heating for amine intercalation reaction, separating, cleaning, and drying, amine intercalation compound (iron chloride-An-GICs) is obtained, heat treating iron chloride-An-GICs (Iron(III) chloride amine graphite intercalation compounds) results in formation of FeXa.
