[资源] Adv. Funct. Mater 以Ni （OH）2 /石墨烯和多孔石墨为电极的超级电容器

这是发表在Adv. Funct. Mater上，题目：Advanced Asymmetric Supercapacitors Based on Ni(OH) 2 /Graphene and Porous Graphene Electrodes with High Energy Density，主要讲述了以Ni （OH）2 /石墨烯和多孔石墨为超级电容器电极，以其独特的结构显示了非常好的电化学性能，具有非常高的能量密度和较高的循环寿命。本文引文61篇。
In order to achieve high energy and power densities, a high-voltage asymmetric supercapacitor is successfully fabricated using Ni(OH) 2 /graphene and porous graphene as the positive and negative electrodes, respectively. Because of their unique structure, both of these materials exhibit excellent electrochemical performances. The optimized asymmetric supercapacitor could be cycled reversibly in the high-voltage region of 0–1.6 V and displays intriguing performances with a maximum specifi c capacitance of 218.4 F g − 1 and high energy density of 77.8 Wh kg − 1 . Furthermore, the Ni(OH) 2 /graphene//porous graphene supercapacitor device exhibits an excellent long cycle life along with 94.3% specifi c capacitance retained after 3000 cycles.
