A solid solution lithium-containing transition metal oxide includes a compound represented by chemical formula (1): [Chem. 1] Li 1.5 [Ni a Co b Mn c [Li] d ]O 3 (where a, b, c and d satisfy relationships: 0.39‰¤a<0.75, 0‰¤b‰¤0.18, 0<c<1.00, 0.05‰¤d‰¤0.25, and a+b+c+d=1.5). The use of the solid solution lithium-containing transition metal oxide in a lithium ion secondary battery can contribute to decreasing the amount of hysteresis of the battery, achieving high energy efficiency, and ensuring a high discharge capacity. |
