Enhanced cyclic stability of LiNi0.8Co0.1Mn0.1O2 (NCM811) by AlF3 coating via atomic layer deposition

LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811) is a promising cathode material for lithium-ion batteries due to its high energy density and low cost. However, NCM811 suffers from poor cycling stability and storage sensitivity to air and moisture. This study introduces an AlF 3 protective layer onto the surface...
