description The invention discloses slurry suitable for coating a positive electrode of a lithium-manganese battery as well as a preparation method and application of the slurry. Preparation raw materials of the slurry comprise a dry powder material, water and a binder glue solution, the dry powder material comprises a conductive agent, a thickening agent and a main material manganese dioxide, and the binder glue solution comprises a water-based binder glue solution and a polytetrafluoroethylene emulsion. The slurry provided by the invention can effectively solve the problem of slurry sedimentation, and coating of the slurry and battery performance are not affected. 本发明公开了一种适用于锂锰电池正极涂布的浆料及其制备方法和应用。所述浆料的制备原料包括干粉料、水和粘结剂胶液，所述干粉料包括导电剂、增稠剂和主材二氧化锰，所述粘结剂胶液包括水性粘结剂胶液和聚四氟乙烯乳液。本发明提供的浆料能够有效解决浆料沉降的问题，而且不影响浆料的涂布及电池性能。
