摘要：

Designing and fabricating unique nanostructured MnO2 electrode to improve their electronic conductivity for supercapacitor application with high electrochemical performance in terms of high specific capacitance, excellent cycle stability, and good rate capability, is still a big challenge. In this work, we report novel nickel foam supported 3D plate-like MnO2 materials as binder-free electrodes for supercapacitors. Benefiting from the unique 3D architectures, the as-obtained MnO2 electrode possesses a high specific surface area of 60.8 m2 g−1, exhibits a high specific capacitance of 680....
