Abstract:Layered Na−Fe−Mn-based cathode materials Na 0.67 Ni 0.11 Cu 0.11 Fe 0.3 Mn 0.48 O 2 (NCFM) for sodium-ion batteries are prepared by a spray drying method in this report. The effect of calcination temperature on NCFM's morphology, structure, and electrochemical properties is investigated in detail. The results show that with the rising temperature from 700 to 900 °C, the proportion of the P2 phase in the asprepared material gradually increases, the pure P2 phase appears at 900 °C, the particle size increases fr… Show more
