Positive slurry contains lithium iron phosphate, conductive graphite, nanocarbon fiber, dispersant which is non-ionic surface active agent and polyvinylidene fluoride. Slurry is homogeneously distributed on upper and lower surfaces of positive current collector.    USE - Quickly chargeable ultrahigh-rate lithium iron phosphate polymer lithium-ion battery.    ADVANTAGE - The ultrahigh-rate lithium iron phosphate polymer lithium-ion battery has high durability, stability and high-speed charging property.    DETAILED DESCRIPTION - A quickly chargeable ultrahigh-rate lithium iron phosphate polymer lithium-ion battery has positive plate, negative plate, isolating membrane and aluminum-plastic composite film which covers positive plate, negative plate and isolating membrane. Positive plate contains positive current collector and positive slurry with solid content of 46-52% and surface density of 15-20 mg/cm2. Positive slurry comprises (in weight%) lithium iron phosphate (88-93), conductive graphite (0.2-2.5), nano-carbon fiber (1-5), dispersant (0.1-0.4) which is non-ionic surface active agent and polyvinylidene fluoride (3.8-6). Slurry is homogeneously distributed on upper and lower surfaces of positive current collector. An INDEPENDENT CLAIM is included for manufacture of quickly chargeable ultrahigh-rate lithium iron phosphate polymer lithium-ion battery. The conductive graphite and the nanocarbon fiber are mixed to form conductive agent. The conductive agent and the lithium iron phosphate are baked at 100-120 degrees C for 4-6 hours in vacuum with vacuum degree of less than -0.08 MPa. The polyvinylidene fluoride is added to 50-60% of N-methylpyrrolidone to form mixed solution (A). The mixed solution (A) is stirred at 40-60 degrees C for 4-6 hours in vacuum. The dispersant and the conductive agent are added to 40-50% of N-methylpyrrolidone to form mixed solution (B). The mixed solution (B) is stirred for 2-3 hours in vacuum. The mixed solution (B) is added to the mixed solution (A), to obtain mixed solution (C). The mixed solution (C) is stirred in vacuum under a circulation of water to cool for 1.5-2.5 hours. Then, the baked lithium iron phosphate is added to the mixed solution (C) to form semi-finished product of slurry. The semi-finished product of slurry is stirred for 2-3 hours, to obtain positive slurry. The positive slurry is applied to upper and lower surfaces of positive current collector, to obtain positive plate. The obtained positive plate is used to obtain quickly chargeable ultrahigh-rate lithium iron phosphate polymer lithium-ion battery.
