Herein, hybrid CoMoO4–NiMoO4 nanosheets (NSs) with mesoporous morphology were assembled using a chitosan hydrogel assisted calcination method. This unique architecture provides numerous channels for rapid diffusion of electrolyte ions, fast electron transfer and high electrochemical activity due to the synergistic effect between the CoMoO4 and NiMoO4. The assembled CoMoO4–NiMoO4 hybrid material can be a very good supercapacitor electrode, due to its high specific capacitance of 1940 F g−1 at the current density of 1 A g−1. Even at a current density as high as 20 A g−1, the CoMoO4–NiMoO4 electrode still delivers a high specific capacitance of 1280 F g−1, indicating its superior rate of specific capacitance 65.98% and excellent cycling stability with capacitance retention 99% after 5000 cycles. Furthermore, the as-prepared CoMoO4–NiMoO4 was employed as anode and activated carbon was used as cathode for solid-state asymmetric supercapacitor. Asymmetric supercapacitors with high power density and energy density (53.33 W h kg−1 at a power density of 800 W kg−1) were realized by improving the potential window with the voltage range from 0 to 1.6 V. These results indicate that the CoMoO4–NiMoO4 electrode shows potential application for high performance, environmentally friendly, and low-cost energy storage device.

The hybrid CoMoO4–NiMoO4 nanosheets with mesoporous morphology were assembled using chitosan hydrogel assisted calcinations method. This unique architecture composites exhibit high specific capacitance of 1940 F g−1 at the current density of 1 A g−1. Even at current density as high as 20 A g−1, the CoMoO4–NiMoO4 electrode still delivers a high specific capacitance of 1280 F g−1, indicating its superior rate of specific capacitance 65.98%.
