摘要： Disclosed is a cathode plate for a secondary battery, which includes a collector, and a cathode active material layer, wherein the cathode active material layer is formed of multiple layers of coating films formed on a surface of the collector and obtained by application and drying of an aqueous paste, which is obtained by kneading and dispersing an iron lithium phosphate material having an olivine structure as the cathode active material, an electroconductive material, a water-soluble thickner, a binder, and water as a dispersion medium.
