Review and prospects of Mn-based spinel compounds as cathode materials for lithium-ion batteries

Abstract

Lithium-ion batteries are one of the most promising electrochemical power sources to be widely used in portable electronics, electric vehicles, and stationary energy storage systems. Mn-based spinel compounds have been intensively investigated as cathode materials for lithium-ion batteries due to their low cost, high safety, and excellent cycling stability. This work reviews the latest advances in exploration and development of Mn-based spinel compounds, including LiMn2O4 and LiNi0.5Mn1.5O4, as high performance cathode materials for lithium-ion batteries. The relationship between the electrochemical properties and composition, structure, morphology are summarized and analyzed. The prospects of the Mn-based spinel compounds as cathode materials for lithium-ion batteries are also looked forward to.
