Improved Electrochemical Performance of Li-Rich Cathode Materials via Spinel Li₂MoO₄ Coating.

ABSTRACT: Li-rich manganese-based cathode materials (LRMs) are considered one of the most promising cathode materials for the next generation of lithium-ion batteries (LIBs) because of their high energy density. However, there are problems such as a capacity decay, poor rate performance, and continuous voltage drop, which seriously limit their large-scale commercial applications. In this work, Li_1.2Mn_0.54Co_0.13Ni_0.13O₂ coated with Li₂MoO₄ with a unique spinel structure was prepared with the wet chemistry method and the subsequent calcination process. The Li₂MoO₄ coating layer with a spinel structure could provide a 3D Li⁺ transport channel, which is beneficial for improving rate performance,
