▎ 摘  要

NOVELTY - Preparation of positive electrode slurry involves drying 92-95 %mass lithium iron phosphate, 1-3 %mass SP and 0.5-1.5 %mass graphene, adding 2-4 %mass adhesive and 40-45 %mass N-methyl pyrrolidone, and obtaining slurry having viscosity of 5000-10000 cP. USE - Preparation of positive electrode slurry for lithium iron phosphate battery. ADVANTAGE - The lithium iron phosphate battery using the positive electrode slurry has excellent conductivity and cycle performance.
