LiMn₂O₄ (LMO) is the substance of choice for small and medium-sized energy storage materials in daily life. In this work, Li₃InCl₆ (LIC) is prepared on the surface of LiMn₂O₄ by hydrothermal method using InCl₃ and LiCl as raw materials. This method stabilizes the LMO crystal structure by uniformly coating the LIC on the LMO surface and effectively maintains the morphology of LMO crystals during the cycling process. SEM and EDS analysis confirm the morphology and homogeneity of the synthesized material LIC on the LMO surface. The prepared material is put into a battery, and the charge-discharge test is carried out at 0.5 C and 1 C. The results show that the LIC surface-modified samples exhibit more than 6% higher cycling performance than the unmodified samples after long cycling.

LiMn ₂ O ₄ (LMO)是日常生活中中小型储能材料的首选物质。在这项工作中，使用InCl _{3通过水热法在LiMn 2} O ₄表面制备了Li ₃ InCl _{6 (LIC)}和氯化锂为原料。该方法通过在LMO表面均匀涂覆LIC来稳定LMO晶体结构，并在循环过程中有效地保持LMO晶体的形态。SEM 和 EDS 分析证实了 LMO 表面上合成材料 LIC 的形态和均匀性。将制备好的材料放入电池中，分别在0.5C和1C下进行充放电测试。结果表明，经过LIC表面修饰的样品在长循环后表现出比未改性样品高6%以上的循环性能.
