Hierarchical spinel NiCo2O4 nanowires were synthesized by a facile hydrothermal method followed by an annealing treatment. The prepared NiCo2O4 nanowires presented a hierarchical mesoporous structure. Moreover, the effects of precipitant and solvent on morphologies of NiCo2O4 were researched. The results reveal that the hierarchical mesoporous structured NiCo2O4 exhibited corking supercapacitor performance with a high specific capacitance of 2876 F·g–1 at a current density of 1 A g–1, even increased to 10.0 A g–1, the specific capacitance could still remain 1290 F g–1, what’s more, the capacitance retention reached 84.7% after 500 cycles, which indicates an excellent electrochemical performance. The results demonstrate hierarchical mesoporous NiCo2O4 potential to be a promising supercapacitor electrode materials and inspire furthered research on binary metal oxides as charge storage materials and offer a new route for the large-scale production of high-performance supercapacitor electrode materials.

用于高性能超级电容器的尖晶石型NiCo 2 O 4纳米线的制备
通过简便的水热方法，然后进行退火处理，合成了尖晶石型NiCo 2 O 4纳米线。制备的NiCo 2 O 4纳米线呈现出分层的中孔结构。此外，研究了沉淀剂和溶剂对NiCo 2 O 4形貌的影响。结果表明，在1 A g –1的电流密度下，分层的介孔结构NiCo 2 O 4表现出具有超级电容的性能，具有2876 F·g –1的比塞超级电容器性能，甚至增加到10.0 A g –1。，比电容仍可保持1290 F g –1，而且，经过500次循环后，电容保持率达到84.7％，这表明它具有出色的电化学性能。结果表明，分层的介孔NiCo 2 O 4潜力是一种有前途的超级电容器电极材料，并激发了对以二元金属氧化物作为电荷存储材料的进一步研究，并为大规模生产高性能超级电容器电极材料提供了一条新途径。
