Summary: A novel O3-NaMn0.42Fe0.42Ni0.17O2 cathode material for sodium-ion batteries was successfully synthesized using a co-precipitation method followed by solid-state reaction. The substitution of Ni2+, Cu2+, and Ca2+ for Fe3+ and Mn4+ improved the structural stability and electrochemical performance of the O3-NaMn0.33Fe0.33Ni0.21Cu0.08Ca0.04O2 cathode material. When combined with a hard carbon anode, the full cell exhibited an energy density of 220 Wh kg(-1) and 100% capacity retention after 56 charge/discharge cycles.
