The present invention provides a single-phase lithium-deficient lithium multicomponent transition metal oxide having a layered crystal structure represented by Li 1-a M1 1-xyz M2 x M3 y M4 z O 2. . Here, M1 is one or more transition metals having an oxidation number of +3, M2 is one or more transition metals having an oxidation number of +4, and M3 is one or more transition metals having an oxidation number of +5. , M4 is one or more elements having an oxidation number of +2, x + 2y−z> 0, x + y + z <1, 0 <a <1, 0 <x <0.75, 0 ≦ y <0.6, 0 ≦ z <0.3.
