Abstract
A cathode material made of cobalt-free layered oxide. A primary particle of the cathode material includes a lithium-poor phase LiMOand a lithium-rich phase LiM'Owhich are of a layered-like structure. Coordination between these two phases is capable to address an issue of low energy density, low initial coulombic efficiency, and low lithium utilization of conventional cobalt-free layered cathode materials. The novel cobalt-free layered cathode material can be applied to lithium-ion batteries to achieve a low cost and high energy density.
