NOVELTY - Oily graphene slurry comprises 0.2-10 wt.% graphite, 0.3-3 wt.% dispersant, 0.01-2 wt.% stabilizing agent, 0.1-3 wt.% first binder and the balanced amount of first solvent. USE - Oily graphene slurry for preparing lithium iron phosphate cathode slurry for battery. ADVANTAGE - The oily graphene slurry can significantly improves the conductivity of the lithium iron phosphate cathode slurry, effectively promotes the transmission and deintercalation of lithium ions, improves the defects such as low reversible capacity and poor rate performance of lithium iron phosphate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing oily graphene slurry, which involves dispersing the graphene in the first solvent added with the dispersant, obtaining graphene solution, vacuum stirring graphene solution, planetary ball milling, and sand-milling, adding first binder and the stabilizer, carrying out secondary vacuum stirring; (2) a lithium iron phosphate positive electrode slurry, which comprises oily graphene slurry; (3) a method for preparing lithium iron phosphate positive electrode slurry, which involves adding the lithium ironphosphate in the oily graphene slurry, obtaining mixed solution, taking thesecond binder is dissolved in the second solvent to obtain binder solution, adding the binder solutioninto the mixed solution and magnetically stirring to obtain the iron phosphate lithium positive electrode slurry; and (4) a battery, which comprises a positive electrode sheet prepared by the method for preparing a lithium iron phosphate cathode slurry or a lithium iron phosphate cathode slurry.
