POSITIVE ELECTRODE ACTIVE MATERIAL, AND LITHIUM SECONDARY BATTERY INCLUDING THE SAME |
摘要 |
Positive electrode active materials are provided. The positive electrode active materials includes a primary particle formed of a plurality of metals including a first metal and a secondary particle formed of at least one of the primary particle. The secondary particle (E2) includes a core part (210), a shell part (220), a seed region (310) where the primary particle having concentration gradient of the first metal is disposed and a maintain region (330) where the primary particle having constant concentration of the first metal is disposed, the seed region adjacent to the core part and a maintain region adjacent to the shell part, and length of the seed region in a direction (230) from the core part to the shell part is 1 µm. |
