Abstract
β-Ni(OH)(2) was constructed into a three-dimensional mesoporous film on Ni foam with ultra-thin (∼6 nm) primary nanowalls showing ultrahigh specific capacitance (2675 F g(-1)) and excellent cycling performance (>96% for 500 cycles). The capacitance was higher than theoretical value possibly due to the combination of Faradic and electrical double-layer capacitances.
摘要
β-Ni(OH)(2) 被构建成具有超薄（∼6nm）初级纳米壁的三维介孔薄膜在 Ni 泡沫上，具有超高的比电容（2675 F g(-1)) 和优异的循环性能（>500 次循环中 96%）。电容高于理论值，可能是由于法拉第和双电层电容的结合。
