▎ 摘　　要

NOVELTY - Preparing graphene complex manganese lithium phosphate material comprises dissolving the lithium hydroxide in the mixed solvent, adding manganese sulfate solution and graphene oxide solution, incubating and adding phosphoric acid solution, subjecting to magnetic stirring, transferring the mixed solution to a reaction vessel for the first hydrothermal reaction, cooling, heating for a second hydrothermal reaction, mixing the solid precursor with glucose and calcining in an inert gas atmosphere. USE - The method is useful for preparing graphene complex manganese lithium phosphate material (claimed). ADVANTAGE - The method: improves the performance of the product; is simple; and can be produced in batch. The material has high product performance. DETAILED DESCRIPTION - Preparing graphene complex manganese lithium phosphate material comprises dissolving the lithium hydroxide in the mixed solvent, adding manganese sulfate solution and graphene oxide solution, to obtain the first solution, ultrasonically stirring, incubating and adding phosphoric acid solution to the first solution for multiple times, to obtain a mixed solution, subjecting the mixed solution to magnetic stirring, transferring the mixed solution to a reaction vessel for the first hydrothermal reaction, cooling the mixture after completion of the reaction, heating for a second hydrothermal reaction, to obtain a solid precursor, mixing the solid precursor with glucose and calcining in an inert gas atmosphere. An INDEPENDENT CLAIM is also included for graphene complex manganese lithium phosphate material prepared by above method.
