Cathode active material having a hollow structure synthesized by co-precipitation method and manufacturing method thereof and lithium secondary battery using the same

摘要

The present invention relates to a positive electrode active material having a hollow structure synthesized by co-precipitation, a method for manufacturing the same, and a lithium secondary battery using the positive electrode active material. According to various embodiments of the present invention, the positive electrode active material comprising lithium transition metal oxide having a hollow structure is formed, thereby making a surface area wider and a diffusion distance of lithium ions shortened, and forming a ternary system having high capacity and stability. Accordingly, when the positive electrode active material is applied to a lithium secondary battery, the capacity, output characteristics, filling density, and lifetime characteristics of the battery can be remarkably enhanced.
