  • Patent number: 10916776
    Abstract: The present invention relates to positive electrode active material particles and a secondary battery including the same and provides positive electrode active material particles comprising: a core including a first lithium transition metal oxide; and a shell surrounding the core, wherein the shell has a form in which metal oxide particles are embedded in a second lithium transition metal oxide, and at least a part of the metal oxide particles is present by being exposed at a surface of the shell. The positive electrode active material particles according to the present invention prevent a transition metal and an electrolyte from causing a side reaction by exposing a part of a metal oxide, having low reactivity, at a surface of the active materials, thereby improving safety and lifespan. As the electrical conductivity of the active materials becomes lower, excellent stability can be maintained even at high temperature and in battery-breakdown situations.
