摘要：

Hierarchical tetragonal microtubes consisting of ultrathin mesoporous NiCo2O4 nanosheets have been obtained by annealing nickel cobalt layered double hydroxide microtubes which are synthesized by a one-step solvothermal method. Benefiting from the unique structural features, these hierarchical NiCo2O4 microtubes manifest an excellent electrochemical performance in terms of high specific capacitance and remarkable cycle life as a battery-type electrode for hybrid supercapacitors.
