Abstract

A facile method for enhancing electrochemical performances of LiCo_1/3Ni_1/3Mn_1/3O₂ cathode material by mixing with Al(OH)₃ additives is reported. The commercial 18,650 size Li-ion cells were manufactured based on Al(OH)₃-mixed LiCo_1/3Ni_1/3Mn_1/3O₂ cathode and artificial graphite anode in a LiPF₆-based non-aqueous electrolyte. The cell with Al(OH)₃-mixed LiCo_1/3Ni_1/3Mn_1/3O₂ cathode exhibits an excellent capacity retention ratio of 63.1% after 300 cycles between 4.3 and 2.75 V at 55 °C, however, that of a pristine cell is only 29.7%. In contrast of the pristine cell, the storage stability of the Al(OH)₃-mixed LiCo_1/3Ni_1/3Mn_1/3O₂ cell is also enhanced greatly. It is found that reducing unwanted side-reactions on cathode with the electrolyte by adsorbing trace amounts of HF in the electrolyte lead to improvement in the electrochemical performances of Al(OH)₃-mixed LiCo_1/3Ni_1/3Mn_1/3O₂ cells.
