Oxygen loss is the current mainstream explanation for voltage decay of Li-rich Mn-rich oxide cathode (LMR), which is conflictive with the ineffectiveness of trivial to stabilize its lattice oxygen and voltage decay. The unclear voltage decay mechanism of high-capacity Li-rich cathode hinders its commercial applications. In this finding, the driving force of voltage decay in LMR is attributed to its lattice displacement/strain, which is concluded by state-of-the-art multiscale characterizations and theoretical calculations, and harmonizes many aspects in this field. Dispersing the Li@Mn6 units in layered structure is an effective method to stabilize the structure of LMR.
