| titleOfInvention | Cathode active material and secondary battery including same |
| abstract | The present invention (a) a first lithium-containing metal composite oxide; And (b) a second lithium-containing metal composite oxide coated on the entire surface of the first lithium-containing metal composite oxide particle, wherein the second lithium-containing metal composite oxide is less than the first lithium-containing metal composite oxide. It provides a positive electrode active material and a secondary battery comprising the same, which is characterized by high resistance and low potential (Li / Li + ) compared to lithium. According to the present invention, a second lithium-containing composite metal oxide having a high resistance and having a lower potential (Li / Li + ) compared to lithium is coated on the entire surface of the first lithium-containing composite metal oxide particle, so that the secondary battery may be discharged from the negative electrode to the positive electrode during internal short-circuit. By reducing the transfer rate of a large amount of lithium ions and electrons transferred, it is possible to prevent heat generation due to instantaneous overcurrent generation, to increase the decomposition and gas generation temperature of the positive electrode active material, suppress the side reaction between the positive electrode active material and the electrolyte Thermal stability can be improved. |
