Binary metal sulfide-based electrode materials with distinct nanoarchitecture, improved conductivities, and fascinating mechanical stabilities are required for the development of nearly all energy storage devices with promising energy density, power density, and stability. Herein, binder-free electrodes were fabricated by direct growth of zinc sulfide-doped manganese (ZnS@Mn) on nickel foam (NF) using hydrothermal method. Different hydrothermal heating times and temperatures were employed to develop the best optimized electrodes for the supercapattery. The synthesized ZnS@Mn nanostructures were characterized through X-ray diffraction structural analysis and morphology studies were conducted using field emission scanning electron microscopy and high-resolution transmission electron microscopy. The electrochemical studies reveal that 6 h of heating at temperature of 150 degrees C had achieved significantly improved specific capacitance of 2913 Fg(-1) and 1722 Fg(-1) at 1 Ag-1 and 10 Ag-1, respectively, while exhibiting an excellent rate capability of 59% at 10 Ag-1. A supercapattery was assembled using the best optimized electrode results in maximum specific capacitance of 263 Fg(-1) with an energy density and power density of 9.14 Wh kg(-1) and 249.95 W kg(-1), respectively.
