NOVELTY - A core-shell multi-dimensional network type lithium vanadium phosphate material is obtained by reacting lithium source, phosphorus source, vanadium source, graphene and complexing organic substance to obtain a precursor of a lithium vanadium phosphate complex, loading obtained complex on graphene sheet and sintering the precursor at 300-900 degrees C under an inert atmosphere to obtain finished product. USE - Core-shell multi-dimensional network type lithium vanadium phosphate material. ADVANTAGE - The multi-dimensional network type lithium vanadium phosphate material can be prepared with uniform nano core-shell structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing core-shell multi-dimensional network type lithium vanadium phosphate material, which involves dissolving lithium source, phosphorus source and vanadium source in deionized water with stoichiometric ratio under magnetic stirring to obtain 1-5 mole/L of mixed solution A, weighing complexing organic substance according to the total molar amount of the metal salt of 1:0.5-1.5 and dispersing graphene in deionized water to give a complexing agent-graphene suspension B, heating the mixed solution A at constant temperature of 50-90 degrees C using magnetic stirrer, pouring the suspension B into solution A, regulating pH value to 1-9, aging the dried sol, gelating the sol and drying the sol to obtain multi-dimensional network of core-shell type lithium vanadium phosphate precursor, and sintering the precursor at 300-500 degrees C for 3-6 hours under an inert atmosphere, in a tube furnace, calcining at 750-900 degrees C for 12-24 hours, followed by cooling, grinding and sieving to obtain the finished product.
