Oxygen defect engineering for the Li-rich cathode material Li1.2Ni0.13Co0.13Mn0.54O2-δ

Takashi Nakamura et al.

Summary: Anion doping is a promising approach to improving battery performance by utilizing anion defects. By quantitatively controlling the oxygen vacancy concentration in Li1.2Ni0.13Co0.13Mn0.54O2-delta, it was found that oxygen vacancies can cause crystal lattice expansion and selective reduction of Ni and Co, resulting in better energy density retention and mitigation of voltage decay in the cathode material. These findings demonstrate the effectiveness of oxygen defect engineering for oxide-based battery materials.
