Hierarchical porous CoNi/CoO/NiO composites derived from dealloyed quasicrystals as advanced anodes for lithium-ion batteries

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.124
