Abstract

Vacancies have been proved effective in activating the oxygen redox and stabilizing the structure of the oxide cathode materials for the Na-ion batteries, but their effect on the cathode materials of the Li-ion batteries is unclear. We herein show that they have similar effect on spinel [Li_4/7Mn_2/7□_1/7]_8a[Li_4/7Mn_10/7]_16d[O_4-x']_32e.
