Composite Particles, Methods of Making the Same, and Articles Including the Same

摘要

Composite particles include a core comprising a layered lithium metal oxide having an O3 crystal structure. A shell layer having an O3 crystal structure encloses the core. The shell layer includes an oxygen-loss, layered lithium metal oxide. The core comprises from 30 to 85 mole percent of the composite particles. A cathode and a lithium-ion battery including the composite particles, and methods of making the foregoing are also disclosed.
