PROBLEM TO BE SOLVED: To provide a high energy density battery which is operable in high electric potential by forming a positive electrode active material of a metallic iodate compound. SOLUTION: In a positive electrode 5, an iodate compound or a metallic iodate compound containing one or more kinds from among Fe, Co, Cu, Zr and Ag is used as a positive electrode active material, and when manufacturing a pole plate, a mix by mixing 10 pts.wt. of polyvinylidene fluoride of a binding agent and 5 pts.wt. of acetylene black of a conductive agent to 85 pts.wt. of either of various metallic iodate compounds, is molded on a current collector 3. Such various iodate compounds function as a positive electrode material of a nonaqueous electrolyte secondary battery, and particularly, the metallic iodate compounds containing one or more kinds from among Fe, Co and Cu are high electric potential, and are also superior in capacitive density. When this positive electrode material is used for the nonaqueous electrolyte secondary battery, nitride, oxide or an alloy containing lithium metal and lithium can be used as a negative electrode active material. |
