Abstract

LiNi_1/3Co_1/3Mn_1/3O₂ particles were coated with Al₂O₃ nanoparticles by means of a mechanochemical bonding process; SEM confirmed that the Al₂O ₃ particles were uniformly coated over the surface of the LiNi _1/3Co_1/3Mn_1/3O₂ powder. During subsequent electrochemical testing using pouch cells, uncoated LiNi _1/3Co_1/3Mn_1/3O₂ exhibited a gradual capacity fading and an increase in area specific impedance (ASI) at a 50% state of charge. Under the same conditions, the increase in ASI of the Al ₂O₃ modified samples was significantly suppressed, although the initial performance (charge/discharge capacity and ASI) slightly deteriorated. The Al₂O₃ coating was also effective in improving the cyclability of LiNi_1/3Co_1/3Mn _1/3O₂ at elevated temperatures by reducing the extent of cracking.
