The fabrication of energy storage devices with lowering the cost and improving the performance has always been the need for society. Therefore, supercapacitors with special features such as light-weight, easy portability and remarkable charging/discharging rate capability have widely been studied in the literature. In the present work, In-situ carbon coated manganese oxide nanorods (ISCC-MnO2NRs) have been studied for the supercapacitor application. ISCC-MnO2NRs were prepared by slip casting method followed by annealing at 1200 °C. During heat treatment, sucrose has transformed into conducting carbon and coated on the surface of MnO2. ISCC-MnO2NRs were examined by FEG-SEM, FEG-TEM, XRD, FT-IR, BET and Raman spectroscopy.
