| Abstract | A facile composite of titanium dioxide nanosheets/nickel–aluminum layered double hydroxide (TiO2/Ni–Al LDH) is fabricated successfully as the electrode material for supercapacitors. The results of scanning electron microscopy and transmission electron microscopy reveal that Ni–Al LDH platelets homogeneously grow onto the surfaces of the TiO2, keeping the neighboring sheets separate. The composite exhibits higher specific capacitance (744.5 F g−1 at a current of 10 mA cm−2) than Ni–Al LDH (519.5 F g−1 at a current of 10 mA cm−2) and 70.7% retained specific capacitance after 4000 cycles in three-electrode system. The unique structure is beneficial for electrode materials because of its sufficient utilization of laminates and high efficiency of transmission for both electrolyte ions and electrons. |
