▎ 摘 要
NOVELTY - A lithium ion battery positive electrode slurry comprises solid material and solvent. The solid material comprises 0.7-2 wt.%, preferably 0.7 wt.% graphene powder, lithium iron phosphate and polyvinylidene fluoride. USE - Lithium ion battery positive electrode slurry used for preparing positive electrode sheet (claimed). ADVANTAGE - The positive electrode slurry has low resistivity of 2.1 ohm.cm, and self-potential resistivity of lower than 7%. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of positive electrode slurry comprising dissolving polyvinylidene fluoride in 67-82% of solvent at 30-40 degrees C for 0.5-1 hour, adding graphene powder, stirring for 1-1.5 hours, adding to the cathode material, adding remaining solvent, and stirring for 0.5-1 hour; and (2) preparation of lithium ion battery positive electrode sheet c2omprising coating positive electrode slurry into aluminum foil, drying, pressing, and cutting.
