| description | The present application provides a positive electrode active material, a method of preparing the same, and a lithium secondary battery including a positive electrode including the positive electrode active material. The positive electrode active material includes: nickel-based lithium metal oxide monolithic particles having an average size of about 1 [mu] m to about 4 [mu] m; and a coating layer containing a cobalt compound on a surface of the nickel-based lithium metal oxide monolithic particle, wherein the nickel-based lithium metal oxide monolithic particle is doped with molybdenum.
本申请提供了正极活性物质、制备正极活性物质的方法以及包括包含正极活性物质的正极的锂二次电池。正极活性物质包括：镍类锂金属氧化物整体颗粒，镍类锂金属氧化物整体颗粒具有约1μm～约4μm的平均尺寸；以及镍类锂金属氧化物整体颗粒的表面上的含有钴化合物的涂层，其中镍类锂金属氧化物整体颗粒掺杂有钼。 |
