Abstract Li‐rich oxides are the most promising of high‐voltage cathode materials with their high specific capacity. However, suffer from structural instability, voltage degradation, and capacity fading upon cycling. Al‐doping can improve electrochemical performance by stabilizing structure suppressing phase transitions for cathodes. In this paper, we investigate effect different amounts Al general formula Li 1.2 Mn 0.54‐x Ni 0.13 Co x O 2 1.2‐x 0.54 (x=0.02, 0.05, 0.1) materials. The elements were replaced Al, was compared to pristine . compared. impact substitution on morphological properties has been investigated scanning electron microscopy (SEM) X‐ray diffraction (XRD). charge discharge tests show that doping leads improved performance, enhancing both cycling stability rate capability Along capacities, these demonstrate superior particularly composition lowest content.
