Document Type and Number:
WIPO Patent Application WO/2019/190217
Kind Code:
A1
Abstract:
A cathode active material precursor according to embodiments of the present invention comprises nickel (Ni) and cobalt (Co), the nickel being contained at an excessive amount, wherein the ratio of the area (A101) of the (101) plane peak to the area ((A 001) of the (001) plane peak, A101/A 001, according to X-ray diffraction analysis is 1 or greater. The cathode active material precursor can be used to attain a cathode and a lithium secondary battery, which are excellent in the degree of crystallization and long-term stability.
