Improved Electrochemical Properties of LiMnO-Based Cathode Material Co-Modified by Mg-Doping and Octahedral Morphology.

In this work, the spinel LiMnO cathode material was prepared by high-temperature solid-phase method and further optimized by co-modification strategy based on the Mg-doping and octahedral morphology. The octahedral LiMnMgO sample belongs to the spinel cubic structure with the space group of Fd3m, and no other impurities are presented in the XRD patterns. The octahedral LiMnMgO particles show narrow size distribution with regular morphology.
