文摘

•: Li_1−xAl_x(Ni_0.5Co_0.2Mn_0.3)_1−yAl_yO₂ (NMCA) are synthesized by solid-state method.
•: LiAlO₂ phase with high Li⁺ ion diffusivity appears in Li_1−xAl_xNi_0.5Co_0.2Mn_0.3O₂.
•: Al prefers to form AlO solid solution in Li(Ni_0.5Co_0.2Mn_0.3)_1−yAl_yO₂ samples.
•: AlO solid solution improve the structural stability of LiNi_0.5Co_0.2Mn_0.3O₂.
•: Substitution of Li with low Al content has superior advantages for NMCA.
