The search for a method for enhancing the electrochemical performance of manganese dioxide is still a challenge. Herein, we report a rod-like P-MnO cathode material with a hierarchical manganese gradient valence through the phosphatization process. For the incorporation of P, MnO was formed on the surface of MnO and exhibited a gradient valence structure, while the oxygen defect concentration in P-MnO increased.
