Abstract

A lithium transition metal oxide capable of minimizing a side reaction with an electrolyte, thereby suppressing the generation of gas during charging and discharging of a lithium secondary battery is provided. A lithium transition metal oxide is represented by Chemical Formula 1, wherein a lattice parameter of a unit lattice satisfies Equations 1 and 2. A positive electrode additive for a lithium secondary battery, and a lithium secondary battery are also provided.
