PROBLEM TO BE SOLVED: To provide a lithium secondary battery excellent in charge/discharge characteristics compared with a lithium secondary battery with an active material of MoO3. SOLUTION: One of positive and negative electrodes has an active material of lithium containing composite oxides of orthorhombic system expressed by a formula MxMo1-xOy or these composite oxides containing Li. In the formula, M is at least one kind of transition element selected from Cu, V, Mn, Fe, Co and Ni and satisfies 0<x<=0.46; 2.6<=y<=3.1. A lithium secondary battery excellent in charge/discharge characteristics compared with a lithium secondary battery used with an active material of MoO3 is provided. |
