Description

Three-dimensional (3D) hierarchical porous CoNi/CoO/NiO composites have been elaborately designed by selectively dealloying of Al-Ni-Co quasicrystals (QCs) alloy. The CoNi/CoO/NiO electrode combines the excellent conductivity and strong stability of CoNi with the high theoretical capacities of CoO/NiO together. When applied as anode materials for lithium-ion batteries (LIBs), the CoNi/CoO/NiO delivers a high specific capacity of 578 mAh g−1 at a current density of 200 mA g 1 after 600 cycles. Furthermore, this facile and efficient strategy not only provides an opportunity for rational designing advanced battery anodes, but also open a promising avenue to explore the application of QCs. - Graphical abstract: Unique CoNi/CoO/NiO composites, derived from Al-Ni-Co quasicrystal precursor alloy, were successfully synthesized by a fancy one-step dealloying method, and exhibited superior electrochemical performance as anode materials.
