Abstract

Thin-iron sulfide films were deposited electrochemically on nickel current collector, and used as cathodes in lithium/composite polymer electrolyte cells. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) tests showed that 0.6-1 μm thick FeS_1+x films were amorphous, with the Fe:S stoichiometry of the films invariant with depth. A Li/CPE/FeS_1+x cells ran at i_d = i_ch = 50μA/cm² (c/1 rate) and 125°C for over 650 charge/discharge cycles with 0.06% per cycle capacity loss and 100% Faradaic efficiency.
