NOVELTY - Preparation of fast conductive modified lithium manganese iron phosphate, involves: 1) grinding lithium manganese iron phosphate anode material to obtain uniform lithium manganese iron phosphate particles; 2) heating lithium manganese iron phosphate particles by feeding a mixed gas containing 40-60 wt.% methane, 20-30 wt.% ethylene and 10-30 wt.% acetylene, reacting under pressure 0.04-0.08 millipascals (MPa), at 300-600°C for 2-3 hours, forming graphene, carbon black and graphite coating on lithium manganese iron phosphate particles to obtain a primary modified lithium manganese iron phosphate; 3) mixing 1-5 wt.% starch and sucrose with primary modified lithium manganese iron phosphate material, heating, reacting, regenerating starch and sucrose, graphene and carbon black coating on the surface of the primary modified lithium manganese iron phosphate material, to obtain a rapidly conductive modified lithium manganese iron phosphate. USE - Method is used for preparing modified lithium manganese iron phosphate used in anode sheet of batteries (claimed). ADVANTAGE - The prepared modified lithium manganese iron phosphate has firm coating structure which is conducive to later processing, and has improved processing performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for fast conductive modified lithium manganese iron phosphate battery anode sheet which is prepared by baking the prepared fast conductive modified lithium manganese iron phosphate, adding conductive agent, solvent and mixed glue to obtain a mixed solution which is coated on a base material.
