Mimics of microstructures of Ni substituted Mn1−xNixCo2O4 for high energy density asymmetric capacitors

The transformation of 3D microstructures of MnCo2O4 into 1D nanowires by incorporation of Ni into Mn site has been demonstrated. Asymmetric capacitor has been fabricated using Mn0.4Ni0.6Co2O4 nanowires as positive electrode and activated carbon (AC) as negative electrode.99
