To optimize the electrochemical performance of lithium manganate (LMO) cathode materials, metal oxides (SnO₂, ZrO₂, La₂O₃, TiO₂) were employed for the coating modification of LMO cathodes. The results show that metal oxide coatings do not change the basic morphology and spinel octahedral structure of LMO cathode materials. The SnO₂-coated cathode material (SnO₂@LMO) exhibits better electrochemical performance than those coated with other oxides. SnO₂@LMO delivers an initial discharge specific capacity of 109.87 mAh/g at 1C rate, with a capacity cycle retention rate as high as 98.01%. At high rates, it shows slower capacity fading and superior rate capability. CV and EIS analyses confirm that the SnO₂ coating forms a stable initial interface, enabling SnO₂@LMO to maintain good reversibility after cycling. SnO₂@LMO has both the lowest surface film resistance (R_s) and charge transfer resistance (R_ct), delivers optimal interface stability and charge transfer kinetics.

为优化锰酸锂（LMO）正极材料的电化学性能，采用金属氧化物（SnO₂、ZrO₂、La₂O₃、TiO₂）对锰酸锂正极材料进行包覆改性。结果表明，金属氧化物包覆不会改变LMO正极材料尖晶石八面体的基本形貌和结构；SnO₂包覆的正极材料SnO₂@LMO样品电化学性能优于其他氧化物包覆的正极材料样品。1C倍率下，SnO₂@LMO首圈放电比容量可达109.87 mAh/g、循环保持率高达98.01%，在高倍率下，容量衰减缓慢，倍率性能更优；CV与EIS分析结果证实，SnO₂包覆层形成了稳定的初始界面，使SnO₂@LMO在循环后仍保持良好的可逆性；SnO₂@LMO表面膜电阻（R_s）与电荷转移电阻（R_ct）均最低，界面稳定性和电荷转移动力学最优。
