Abstract

Theoretically, layered Ni-rich metal oxides are capable of delivering 200 mA h g^-1. However, their performances deteriorate due to an irreversible surface reaction with the electrolyte, which could be overcome by the partial substitution of fluorine for oxygen. Herein, a fluorine-doped, Ni-rich metal oxide with the composition LiNi_0.7Co_0.15Mn_0.15O_1.95F_0.05 exhibited a capacity of 170 mA h g^-1 after 100 cycles when tested against lithium.
