摘要：
One-dimensional nanostructures of ultrathin standing alpha-Ni(OH)(2) nanosheets@halloysite nanotubes are synthesized through one-step facile precipitation method. The nanocomposites exhibit high capacitance (1677 F g(-1)) and excellent cycling stability (100% capacity retention after 2000 cycles) due to their ultrathin and standing nanosheets and intense cation/anion exchange performance of halloysite nanotubes. The remarkable electrochemical performance will undoubtedly make the hybrid structures attractive for high-performance supercapacitors.
