Abstract

The present disclosure relates to a lithium-transition metal-silicate complex that is formed into a sphere with a hollow, in which a radius of the hollow is in a range of 0.5 to 3.0 nm, and a diameter of the lithium-transition metal-silicate complex is in a range of 5 to 10 nm. The present disclosure enables to facilitate the mass production of a complex including a lithium-transition metal-silicate complex, having a micro-sized hollow, and having a spherical shape. In addition, when using a lithium-transition metal-silicate complex of the present disclosure as a cathode active material for a lithium secondary battery, it is capable of providing a cathode active material for a lithium-ion battery excellent in charging and discharging characteristics as well as in high-rate characteristics. In addition, a lithium-transition metal-silicate complex manufactured according to the present disclosure may implement properties of materials of lithium, transition metal, and silicate as well as its structural characteristics, and thus, it can be effectively applied in various industrial fields.
