Title:
NOVEL LITHIUM-METAL OXIDE COMPOSITE, AND LITHIUM SECONDARY BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/066214
Kind Code:
A1
Abstract:
The present invention provides a novel lithium-metal oxide composite comprising nickel (Ni) and titanium (Ti) as the main components, such a lithium-metal oxide composite characterized by having high charge capacity and long service life, and, when used with negative electrode active material having high energy density, providing the optimal performance of a lithium secondary battery, and, particularly, as the charge capacity and optimal balance of Si-based negative electrode active material can be maintained, allowing high performance lithium secondary batteries to be produced.
