A nanoflower structure of Zn[Formula: see text]Co[Formula: see text]S directly grown on carbon fiber papers (CFP) was successfully designed by a mild two-step hydrothermal method. Benefiting from their fascinating structural features, Zn[Formula: see text]Co[Formula: see text]S/CFP electrode exhibits a maximum specific capacitance of 300[Formula: see text]F[Formula: see text]g[Formula: see text] at current density of 1[Formula: see text]A[Formula: see text]g[Formula: see text] and 84% capacitance retention after 5,000 cycles at current density of 5[Formula: see text]A[Formula: see text]g[Formula: see text]. Subsequently, Zn[Formula: see text]Co[Formula: see text]S/CFP//AC all-solid-state asymmetric supercapacitor (ASC) device is assembled and able to illuminate the red LEDs. ASC devices deliver a maximum energy density of 9.59[Formula: see text]W[Formula: see text]h[Formula: see text]kg[Formula: see text] at a power density of 750[Formula: see text]W[Formula: see text]kg[Formula: see text]. Therefore, this impressive result demonstrates that the nanoflower Zn[Formula: see text]Co[Formula: see text]S have promising applications in the development of high-performance supercapacitors.

Carbon Fiber Electrode

Transition metal oxides and hydroxides, specifically nickel (Ni), are currently being studied for their pseudocapacitive behaviors due to their high specific capacitance and efficient redox reactions. In this study, nickel oxide (NiO) and nickel hydroxide [Ni (OH)2] hierarchical structures were grown on carbon fiber paper via hydrothermal treatment for a binder-free electrode for pseudocapacitor. Cyclic voltammetry was employed to determine the influence of annealing temperature on the specific capacitance of NiO-and/or Ni (OH)2 – carbon fiber electrodes. The NiO – carbon fiber electrode annealed at 400°C exhibited the highest specific capacitance of about 1993.12 F/g at a scan rate of 2 mV/s. The carbon fibers were fully covered by NiO platelets which possibly provide efficient transport of electrolyte, enhancing the capacitance.
