N2 - Thin-film molybdenum oxysulfide films were deposited electrochemically on both nickel foils and nickel-coated silicon substrates, and used as cathodes in lithium battery cells that included a lithium anode and a hybride gel electrolyte (HPE) or solid polymer electrolyte (SPE). X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) characterizations indicated that the sub-micron thick MoOySz films were amorphous, with the stoichiometry of the films varying with depth. A Li/HPE/MoOySz on nickel and nickel-coated silicon ran at id=ich=100μA/cm2 and room temperature for 1000 charge/discharge cycles with 0.05% per cycle capacity loss and 100% Faradaic efficiency. Cells with SPE cycled at 125 °C showed a higher per cycle capacity loss of 0.5%.
