Abstract
Electrochemical properties and performance of lithium/polymer electrolyte/composite sulfur cells are presented. The composite sulfur cathode prepared by two ways were characterized and compared by X-ray diffraction (XRD), thermogravimetry (TG), differential thermoanalysis (DTA) and scanning electron microscopy (SEM). The all-solid-state Li/S battery operated at 75 °C with P(EO)20Li(CF3SO2)2N-10 wt.%γ-LiAlO2 as electrolyte exhibited an average capacity of 290 mAh gâ1 for the sulfur melted together with poly(ethylene oxide) (PEO) during 50 cycles. The mechanisms for capacity degradation of the Li/S polymer battery were discussed.
