Abstract

High voltage spinel LiMn <subscript>1.5</subscript> Ni <subscript>0.5</subscript> O <subscript>4</subscript> (LMNO) is a promising energy storage material for the next generation lithium batteries with high energy densities. However, due to the major controversies in synthesis, structure, and interfacial properties of LMNO, its unsatisfactory performance is still a challenge hindering the technology's practical applications. Herein, this paper provides general characteristics of LiMn <subscript>1.5</subscript> Ni <subscript>0.5</subscript> O <subscript>4</subscript> such as spinel structure, electrochemical properties, and phase transition. In addition, factors such as electrolyte decomposition and morphology of LMNO that influence the electrochemical performances of LMNO are introduced. The strategies that enhance the electrochemical performances including coating, doping, electrolytes, and oxygen deficiency are comprehensively discussed. Through the discussion of the present research status and presentation of our perspectives on future development, we provide the rational design of LMNO in realizing lithium-ion batteries with improved electrochemical performances.<br />Competing Interests: The authors declare no competing financial interest.<br /> (© 2024 The Authors.
