Mimics of microstructures of Ni substituted Mn1-xNixCo2O4 for high energy density asymmetric capacitors
The preparation of nanostructured hierarchical MnNiCoO metal oxides as efficient supercapacitors of different structures and configurations especially for the miniaturized electronics is still a challenge. In this context, we report template free facile hydrothermal synthesis of hierarchical nanostr...

| description |
The preparation of nanostructured hierarchical MnNiCoO metal oxides as efficient supercapacitors of different structures and configurations especially for the miniaturized electronics is still a challenge. In this context, we report template free facile hydrothermal synthesis of hierarchical nanostructured MnNiCoO with excellent supercapacitive performance. Significantly, the morphology of pure MnCoO transformed from 3D microcubes to 1D nanowires with incorporation of Ni. The electrochemical study shows highest specific capacitance i.e. 1762 F/g for MnNiCoO with high cycling stability of 89.2% which is much higher than pristine MnCoO and NiCoO. Later, asymmetric capacitor has been fabricated successfully using MnNiCoO nanowires as positive electrode and activated carbon (AC) as negative electrode in a KOH aqueous electrolyte. An asymmetric cell could be cycled reversibly in the high-voltage range of 0-1.5 V and displays intriguing performances with a specific capacitance of 112.8 F/g (6.87 F/cm) and high energy density of 35.2 Wh/kg (2.1 mWh/cm). Importantly, this asymmetric capacitor device exhibits an excellent long cycle life along with 83.2% specific capacitance retained after 2000 cycles. |
