DEVICE FOR PREPARING LITHIUM COMPOSITE TRANSITION METAL OXIDE, LITHIUM COMPOSITE TRANSITION METAL OXIDE PREPARED USING THE SAME, AND METHOD OF PREPARING LITHIUM COMPOSITE TRANSITION METAL OXIDE

摘要

A device for preparing a lithium composite transition metal oxide includes first and second mixers continuously arranged in a direction in which a fluid proceeds, wherein the first mixer has a closed structure including a hollow fixed cylinder, a rotating cylinder having the same axis as that of the hollow fixed cylinder and having an outer diameter that is smaller than an inner diameter of the fixed cylinder, an electric motor to generate power for rotation of the rotating cylinder, a rotation reaction space, as a separation space between the hollow fixed cylinder and the rotating cylinder, in which ring-shaped vortex pairs periodically arranged along a rotating shaft and rotating in opposite directions are formed, first inlets through which raw materials are introduced into the rotation reaction space, and a first outlet to discharge a reaction fluid formed from the rotation reaction space.
