AbstractTraditional cathode materials can no longer meet the development needs of thermal batteries, and the research of new cathode materials is imminent. In this study, WS2 was successfully prepared by a simple one-step synthesis method. X-ray photoelectron spectroscopy (XPS) showed that it has good electrical conductivity, its bandgap had been calculated by ultraviolet-visible diffuse reflectance spectroscopy (UV-visDRS), and its thermal decomposition temperature exceeded 1000 degrees C by thermogravimetric (TG) analysis. Due to the high decomposition temperature and high electronic conductivity of WS2, LiBr-LiCl-LiF electrolyte with high ionic conductivity but the high melting point was selected. The structure and composition of WS2 and LiBr-LiCl-LiF after reaction at high temperature (500 degrees C) were studied, and WS2 was found to have good compatibility with ternary lithium electrolyte. Assembling Li-B/LiBr-LiCl-LiF/WS2 single thermal battery, the discharge specific capacity is 952As g(-1)at 300 mA cm(-2) and cutoff voltage of 0.97 V. And the internal resistance of the single thermal battery is 11.87 m Omega under the super large pulse current density of 5A cm(-2). This further advances the application of WS2 in thermal batteries.
