Abstract

Key findings

  • Al3+ doping increases the capacity of Li1.2Ni0.13Co0.13Mn0.54O2 cathode material by 15%.
  • The doped material shows reduced degradation and improved cycling stability.
  • The improved performance is attributed to the substitution of Al3+ for Ni2+ ions, leading to a more stable crystal structure.
