Wood, becoming a renewable biomass resource, shows lot of potential for various uses. In this work, we developed novel carbonized wood as substrate material, and AgCo-MOF/MnS was deposited on it. This composite material AgCo-MOF/MnS@CWS possesses unique properties such excellent specific capacitance, adaptability, flexibility, the capacity to produce high electrical power. When tested in three-cell assembly, resultant showed remarkable performance by delivering 1068 C/g at 1.0 A/g. A supercapacitor also built merging AgCoMOF/MnS@CWS AC@CWS two-cell configuration. The energy power density AgCoMOF/MnS@CWS//AC@CWS device 50 Wh/kg 830 W/kg, respectively. Additionally, stability measurement indicates that can retain up 98% its initial after 12000 GCD cycles. demonstrates 146 mV overpotential along 45 mV/dec Tafel slope OER application.

Abstract Due to their unique structure, the metal sulfides are mechanically stable, have higher conductivities, and frequently used in energy storage devices. Here, binder-free electrodes were designed by depositing nickel zinc sulfide (NiZnS) incorporated with carbon nanotubes (CNTs) on foam (NF). X-ray diffraction (XRD) was describe crystallinity of produced CNTs-NiZnS nanostructures, morphological investigations performed using field emission scanning electron microscopy (FESEM). According electrochemical measurements, heating electrolyte at 80 °C resulted considerably enhanced specific capacitance 1475 Cg −1 (50.85 F m −2 ) 666 (13.77 1 2 Ag current density, correspondingly.
