摘要	The performances of transition-metal oxides as battery-type electrodes can be effectively enhanced by optimizing their intrinsic properties and integrating conductive components. Herein, an in situ exsolution strategy was used to prepare metallic Cu/mixed oxides heterostructured electrodes that containing multi-cations (Cu2+, Ni2+, and Co2+). The synergetic effects of the uniformly distributed metallic Cu components, a compact metal/oxides interface, and a mesoporous structure ensures that the prepared heterostructured electrodes have enhanced redox reactivity. A Cu@CuNiCoO nanowire electrode gave a high specific capacity (1054 C g−1), and rate capacity, and had superior cycling stability. Our work broadens the scope of metal/oxides heterostructured electrodes for energy storage. © 2021 Elsevier B.V.
