The synthesis of a new layered cathode material, Na 0.5 [Ni 0.23 Fe 0.13 Mn 0.63 ]O 2 , and its characterization in terms of crystalline structure and electrochemical performance in a sodium cell is reported. X‐ray diffraction studies and high resolution scanning electron microscopy images reveal a well‐defined P2‐type layered structure, while the electrochemical tests demonstrate excellent characteristics in terms of high capacity and cycle life. This performance, the low cost, and the environmental compatibility of its component poses Na 0.5 [Ni 0.23 Fe 0.13 Mn 0.63 ]O 2 to be among the most promising materials for the next generation of sodium‐ion batteries.
