Abstract
Bimetal-organic frameworks (BMOFs) have attracted considerable attention as electrode materials for energy storage devices because of the precise control of their porous structure, surface area, and pore volume. BMOFs can promote multiple redox reactions because of the enhanced charge transfer between different metal ions. Therefore, the electroactivity of the electrodes can be significantly improved. Herein, we report a NiCo-MOF (NCMF) with a three-dimensional hierarchical nanorod-like structure prepared using a facile solvo-hydrothermal method. The as-prepared NCMF was used as the positive electrode in a hybrid pouch-type asymmetric supercapacitor device (HPASD) with a gel electrolyte (KOH+PVA) and activated carbon as the negative electrode. Because of the matchable potential windows and specific capacitances of the two electrodes, the assembled HPASD exhibits a specific capacitance of 161 F·g-1 at 0.5 A·g-1, an energy density of 50.3 Wh·kg-1 at a power density of 375 W·kg-1, and a cycling stability of 87.6% after 6000 cycles. The reported unique synthesis strategy is promising for producing high-energy-density electrode materials for supercapacitors.

Abstract
Transition metal oxide-based battery-type electrode materials with well-defined nanostructure have shown great potential in supercapacitors, due to their high electrical conductivity and superior redox activity. Herein, promising CoWO4@WO3-1 heterostructured nanosheets with rich oxygen vacancies are designed via a two-step in situ construction process and following thermal treatment. The CoWO4@WO3-1 heterostructured nanosheet arrays grown on a flexible carbon cloth substrate can provide an effective nanoporous framework, facilitate electrons/ions transport, and generate effective synergistic effect of high conductivity from WO3 and superior redox activity from CoWO4. As a result, the as-prepared CoWO4@WO3-1 electrodes exhibit a high area specific capacity of 578.6 mF cm-2 at a current density of 0.5 mA cm-2 and keep 98.38% capacity retention at 20 mA cm-2 over 30 000 cycles. Additionally, all-solid-state supercapacitors assembled with CoWO4@WO3-1 as cathodes and Ov-NiMoO4 as anodes show a maximum area energy density of 13.93 mW h cm-2 and power density of 6502.11 mW cm-2, keeping outstanding cycling stability of 98.1% capacity retention over 20 000 cycles.
