title: Growing nickel cobaltite nanowires and nanosheets on carbon cloth with different pseudocapacitive performance.
abstract: Controllable synthesis and high yield of functional nanomaterials on conductive substrates are highly desirable for energy conversion and storage applications. In this work, two different porous NiCo2O4 nanoarchitectures (including nanowires and nanosheets) are directly grown on carbon cloth collectors, which display a structure-dependence in their capacitive behaviors. Our results show that the nanowire morphology exhibits higher specific capacitance and better cycling performance in the three-electrode configuration. The pseudocapacitive difference is related to the surface area and pore structure of NiCo2O4 nanocrystals. This comparison among different morphologies reveals a process-structure-property relationship in electrochemical energy storage.
