Enhanced electrochemical performance of Ni-rich LiNi0.6Co0.2Mn0.2O2 coated by molecular layer deposition derived dual-functional C-Al2O3 composite coating

Uniform C-Al2O3 composite coating with homogeneous thickness was adopted to improve the electrochemical properties of LiNi0.6Co0.2Mn0.2O2 by the pyrolysis of molecular layer deposited alucone in argon. Compared with LiNi0.6Co0.2Mn0.2O2 coated atomic layer deposited Al2O3, C-Al2O3 coated electrode delivered high discharge capacity, good rate capability and durable cyclic stability, even at elevated temperature. Such enhanced electrochemical...
