Method of preparing core-shell particles
A method of manufacturing core-shell particles comprises: filling a buffer into a rotor, which is extended in a longitudinal direction, and is accommodated so as to be spaced apart from an inner wall side of a non-rotational hollow cylinder extended in a longitudinal direction and then discharging air to outside; rotating the rotor after terminating the filling; forming a core-shell precursor by supplying raw materials from a first storage and a second storage, which comprise a material forming a core, into an interior of the cylinder in which the rotor rotates; supplying a shell material for coating the core to the interior of the cylinder in which a core-type precursor is formed; separating a liquid comprising core-shell particles formed through the supplying into a solid and a liquid; and drying the core-shell particles obtained through the separating.

filling a buffer into a rotor, which is extended in a longitudinal direction, and is accommodated so as to be spaced apart from an inner wall side of a non-rotational hollow cylinder extended in a longitudinal direction and then discharging air to outside of the rotor;
rotating the rotor after terminating the filling;
forming a core-shell precursor by supplying raw materials from a first storage and a second storage, which comprise a material forming a core, into an interior of the cylinder in which the rotor rotates;
supplying a shell material for coating the core to the interior of the cylinder in which a core-type precursor is formed;
separating a liquid comprising core-shell particles formed through the supplying of the shell material into a solid and a liquid; and
drying the core-shell particles obtained through the separating.
2. The method according to claim 1 , wherein lithium chloride and sodium carbonate; or lithium hydroxide and carbon dioxide; or aluminum carbonate and copper sulfate, as a pair of raw materials, are respectively stored in the first storage and the second storage.
