Hierarchical CuCo 2 O 4 nanowire@NiCo 2 O 4 nanosheet core/shell arrays for high-performance supercapacitors

In this work, CuCo 2 O 4 nanowire@NiCo 2 O 4 nanosheet core/shell arrays were designed and synthesized on Ni foam. Taking the advantage of the synergistic effect and 3D core/shell nanostructure, the hybrid electrode exhibited a notable increased electrochemical performance.
