Nickel oxide nanosheets have been successfully synthesized by a facile ethylene glycol mediated hydrothermal method. The morphology and crystal structure of the nickel oxide nanosheets were characterized by X-ray diffraction, field-emission SEM, and TEM. When applied as electrode materials for lithium-ion batteries and supercapacitors, nickel oxide nanosheets exhibited a high, reversible lithium storage capacity of 1193 mA h g(-1) at a current density of 500 mA g(-1), an enhanced rate capability, and good cycling stability. Nickel oxide nanosheets also demonstrated a superior specific capacitance of 999 F g(-1) at a current density of 20 A g(-1) in supercapacitors.
通过简单的乙二醇介导水热法成功合成了氧化镍纳米片。通过 X 射线衍射、场发射扫描电子显微镜和透射电子显微镜对氧化镍纳米片的形貌和晶体结构进行了表征。将氧化镍纳米片用作锂离子电池和超级电容器的电极材料时，在 500 mA g(-1)的电流密度下，其具有 1193 mA h g(-1)的高可逆锂存储容量、增强的倍率性能和良好的循环稳定性。在超级电容器中，氧化镍纳米片在 20 A g(-1)的电流密度下表现出 999 F g(-1)的优异比电容。
