| titleOfInvention | A kind of preparation method of lithium iron phosphate cathode material |
| abstract | The invention relates to the field of lithium ion batteries, in particular to a preparation method of a lithium iron phosphate positive electrode material. The method includes the following steps: 1) dissolving a certain stoichiometric ratio of lithium source, iron source and phosphorus source in a solvent to obtain a lithium iron phosphate precursor solution; 2) adding graphene to the lithium iron phosphate precursor solution, and drying to obtain graphite Lithium iron phosphate precursor; 3) adding organic carbon source, and calcining to obtain graphene/organic carbon source synergistically coating lithium iron phosphate; 4) carrying out polyaniline deposition modification, and adsorbing zinc oxide quantum dots; the present invention first uses Graphene and organic carbon sources synergistically coat lithium iron phosphate to form a unique 3D conductive network structure, which overcomes the extremely low conductivity of lithium iron phosphate itself. On the surface of graphene, the high conductivity of polyaniline and the p-n structure of zinc oxide quantum dots and polyaniline are utilized to further increase the conductivity of the lithium iron phosphate cathode material. |
