<P>PROBLEM TO BE SOLVED: To provide a manganese oxide which is excellent in a charge and discharge cycle for a long term, where high capacity can be expected and which is important as an inexpensive electrode material for a battery, an electrode active material for a secondary battery, those producing methods and a lithium secondary battery using the electrode active material for the secondary battery. <P>SOLUTION: The manganese oxide has a chemical composition represented by general formula Li<SB>x</SB>Ca<SB>y</SB>Mn<SB>9-z</SB>Ti<SB>z</SB>O<SB>18</SB>(wherein, composition range is 0<x<9; 0<y<1.8; and 0≤z≤5) and contains lithium, calcium, manganese, titanium, and oxygen as main ingredients. There are also provided the electrode active material for the secondary battery, those producing methods, and the lithium secondary battery using the electrode active material for the secondary battery. <P>COPYRIGHT: (C)2010,JPO&INPIT |
