Hydrothermal synthesis of nickel oxide nanosheets for lithium-ion batteries and supercapacitors with excellent performance

Journal Article


Abstract


  • 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. Between the sheets: NiO nanosheets were synthesized by a facile ethylene glycol mediated hydrothermal method (see picture). The NiO nanosheets exhibited a high, reversible lithium storage capacity of 1193 mA h g-1 at a current density of 500 mA g-1 for lithium-ion batteries and a superior specific capacitance of 999 F g-1 at a current density of 20 A g-1 in supercapacitors.
