Substitution of Sr into the Na Layer Elevates the High Voltage Stability of O3‐Type NaCrO2 as Sodium‐Ion Battery Cathode

Substitution of Sr into the Na Layer Elevates the High Voltage Stability of O3‐Type NaCrO2 as Sodium‐Ion Battery Cathode

Herein, the substitution strategy of Sr2+ into Na sites is proposed and its important role in improving the high‐voltage stability of O3‐type NaCrO2 cathode (O3‐NCO) for high‐energy sodium‐ion batteries (SIBs) is systematically analyzed. Sr2+ possesses similar physicochemical characteristics to that...
