摘要	In this paper, we report a hierarchical structure Ni(OH)(2) nanosheet array electrode by a directed liquid-phase approach, which consists of amorphous Ni(OH)(2) interface layer and crystalline ultra-thin porous Ni(OH)(2) nanosheets top layer. The testing results present that the maximum discharge capacity of 404.8mAh g(-1) at lower rate of 1.4 Ag-1 and the ultra-high capacity of 1714 Fg(-1) at super-high rate of 50 Ag-1 without decay after 3000 cycles was obtained, respectively. This unique design provides excellent flexibility, long and stable cycle lifetimes, high energy and power densities simultaneously. (C) 2015 Elsevier Ltd. All rights reserved.
