Aqueous lithium iron phosphate positive electrode slurry as well as preparation method and application thereof

The invention relates to aqueous lithium iron phosphate positive electrode slurry which comprises the following raw materials in parts by weight: 90-94 parts of lithium iron phosphate, 3-5 parts of a conductive agent, 1-1.8 parts of acrylic resin, 1.3-2.5 parts of NV-1A glue, 107-111 parts of deionized water and 5-8 parts of a defoaming agent. The slurry solves the problems of environmental pollution, high cost and the like of an oily system lithium iron phosphate slurry, and the positive electrode slurry has the advantages of high adhesion strength, no cracking, high single surface density and high energy density after being coated. 本发明涉及一种水系磷酸铁锂正极浆料，包括以下重量份比的原料：90-94份磷酸铁锂、3-5份导电剂、1-1.8份丙烯酸树脂、1.3-2.5份NV-1A胶、107-111份去离子水、5-8份消泡剂。该浆料解决了油性体系磷酸铁锂浆料的环境污染和成本较高等问题，且该正极浆料涂布后的粘黏强度高，不开裂，单面面密度高，能量密度高。
