High-capacity Mn-rich layered cathodes suffer from intrinsically unstable anionic redox chemistry. Herein, we report that structural ordering regulation via synthesis temperature effectively stabilizes this anionic redox, achieving 253 mAh g-1 capacity after 100 cycles at 0.1C and over 92% capacity retention after 200 cycles at 1C.
