A three-dimensional nanoporous Ni scaffold on flexible carbon cloth (3D Ni@CC) is used for constructing 3D MnOx electrode.
- class="label">•
The 3D Ni@CC not only increases mass loading of MnOx, but also ameliorates its poor electronic and ionic conductivities.
- class="label">•
An flexible all-solid-state asymmetric supercapacitor (AASC) is assembled using 3D MnOx@Ni@CC and graphene as electrodes.
- class="label">•
The AASC achieves a superior energy density of 1.16 mW h cm−3 and retains 85.7% capacitance after 200 bending cycles.
