POSITIVE ELECTRODE MATERIAL FOR LITHIUM/IRON DISULFIDE PRIMARY BATTERY, AND MANUFACTURING METHOD THEREFOR, AND THE LITHIUM/IRON DISULFIDE PRIMARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a positive electrode material for lithium/iron disulfide primary batteries capable of improving storage characteristics, to provide a manufacturing method of the positive electrode material, and to provide the lithium/iron disulfide primary batteries.;SOLUTION: The positive electrode 2 comprises a positive electrode collector and a positive electrode mixture layer formed on both surfaces of the positive electrode collector. The positive electrode mixture layer has, for example, a positive electrode material where a layer containing triiron tetraoxide (Fe₃O₄) is provided, at least partially on the surface of iron disulfide. By constituting of such a positive electrode material, the storage characteristics can be improved.;COPYRIGHT: (C)2008,JPO&INPIT
