Abstract: Spinel LiMn₂O₄ with three-dimensional diffusion channels of lithium ions has several advantages such as high voltage platform, abundant manganese resource, and environmental friendliness, making it the ideal cathode materials for high-power lithium-ion batteries. Solid-state methods are very important for preparing LiMn₂O₄ cathode materials due the simple sintering equipment operations and relatively low industrial production costs, which may achieve the large-scale production. In this work, the basic principle of solid-state preparation of spinel LiMn₂O₄ cathode materials was elucidated, and various solid-state synthesis strategies for spinel LiMn₂O₄ cathode materials were analyzed, including high-temperature solid-state method, high-energy ball milling method, microwave-assisted solid-state method, etc. Moreover, a detailed review was conducted on the research progress of spinel LiMn₂O₄ cathode materials prepared by using different manganese sources. In addition, the prospect of solid-state synthesis methods for developing the low-cost and high-performance LiMn₂O₄ cathode materials was discussed.
