A lithium ion type nonaqueous electrolyte-secondary battery which comprises a positive electrode which comprises, as an active material, a compound oxide represented by the following chemical formula (I): Lix Ay Mz Jm Op (I> wherein A represents at least one alkali element selected from the group consisting of Na and K; M represents at least one transition element selected from the group consisting of Co, Mn and Ni; J represents an element having a glass-forming ability selected from the group consisting of B, Si, Ge, P, V, Zr, Sb and Ti; 0.8 </= x</=1.3; 0</=y </=0.2; 0.8</=z </=2.0; 0.01 </=m </=0.2; and 2.0</=p </=4.7; a negative electrode; and a nonaqueous electrolyte. The positive electrode-active material permits the production of nonaqueous electrolyte lithium type secondary batteries having excellent charge-discharge characteristics, discharge voltages and cycle properties. |
