Abstract

Ni(OH)(2)/MnO(2) core-shell nanowires with a nanoflake surface have been designed and synthesized, and can be applied not only in neutral electrolytes (355 F g(-1), 70.4 wt% MnO(2)) but are also appropriate for alkaline electrolytes (487.4 F g(-1), 35.5 wt% MnO(2)), with high cycling stability due to the synergistic effect between the core and shell.
