多元掺杂三维多孔镍基全固态超级电容器的研究

Study on Multi-doped Three-dimensional Porous Nickel-based All Solid Supercapacitor

在60℃的离子液体中对NiCo_xO_y/NF三元电极材料进行研究,通过电沉积得到NiCo_xO_y/NF纳米片阵列电极材料,材料表面的元素Ni和Co都是以金属氧化物形式存在且均匀分布。比电容值最高可以达到1 626.7mF/cm^2,且保持率在90.2%。

NiCoxOy/NF ternary electrode materials were electrodeposited in 60 ℃ ionic liquids.The results show that element of Ni and Co in surface both exist in form of metal oxide and uniform distribution.The specific capacitance value can reach a maximum of 1 626.7 mF/cm^2, and the retention rate is 90.2%.
