Abstract
A solid solution lithium-containing transition metal oxide includes a compound represented by chemical formula (1): Li[NiCoMn[Li]]O, 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.
