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 4/7 Mn 2/7 □ 1/7 ] 8a [Li 4/7 Mn 10/7 ] 16d [O 4- x ' ] 32e .
