Enhanced air stability by calcium doping in Na<sub>2/3</sub>[Fe<sub>1/2</sub>Mn<sub>1/2</sub>]O<sub>2</sub> cathode material for Na-ion batteries
Ca doping enhances air stability by forming a Ca-rich surface region, which suppresses Na + /H + exchange and helps retain electrochemical performance after air exposure.
