Abstract
The present invention relates to a method for preparing a lithium composite oxide and a lithium composite oxide prepared thereby and, more specifically, to: a method for preparing a lithium composite oxide, capable of preparing a lithium-ion secondary battery with high capacity by adjusting the amount of a basic solution added according to the nickel content during the preparation of a lithium composite oxide through a co-precipitation reaction, thereby adjusting the pH of the reactor, and thus improving the particle density and increasing the tap density, and a lithium composite oxide prepared thereby.
