Abstract.To enhance the structural and chemical stability of LiNi0.8Co0.1Mn0.1O2 (NCM811), a series of Mo-doped NCM811 electrolytes (Mox-NCM811, x = 0-0.03) were synthesized via high-energy mechanical ball milling followed by high-temperature sintering. XRD phase analysis, GASA II refinement, and SEM characterization revealed that appropriate Mo doping effectively reduces the ion migration impedance, enhances Li+ diffusion coefficient, and stabilizes the material structure, thereby improving both discharge specific capacity and cycling performance. When the Mo doping level reaches x=0.02, the optimized …
