LiMg silicide was obtained by hydrogen reduction of a mixture of silicon and magnesium at high temperature, and characterized by X-ray diffraction and scanning electron microscopy. The results show that the prepared LiMg silicide has good crystallinity and nanocrystalline size.Subsequently, its lithium storage properties were evaluated by electrochemical tests. The results show that the prepared LiMg silicide material exhibits good cycling stability and high specific capacity, indicating that this material is a potential lithium-ion battery anode material. Further studies have found that the lithium storage properties of this material are closely related to its crystal structure and ion transport properties. In addition, detailed discussions were conducted on the cycling stability and rate performance, and suggestions for further research were proposed.Keywords: LiMg silicide, hydrogen-driven chemical reaction, lithium storage properties, electrochemical properties, crystal structure
