Improving electrical conductivity and increasing the active site are important directions for improving technology of manganese-based cathode materials zinc ion batteries (ZIBs). In this paper, cobalt-doped oxygen-vacancy coupled MnO2 nanorods (Vo-CMO) were prepared by defect engineering an doping strategy as rechargeable ZIBs. Oxygen vacancies can increase density material provide more migration paths ions, thereby electrochemical activity specific capacity.
