Abstract:
We successfully prepared an Fe- and Li-containing polysulfide positive electrode material (Li8FeS5-Li2FeS2 composite) that shows a high specific capacity (>500 mA h g-1) with improved rate capability in all-solid-state cells. High-resolution TEM analysis indicated the coexistence of small crystallites of high-conductivity Li2FeS2 and FeS, as well as low-crystallinity Li2S, in the composite, and this microstructure is responsible for the improved battery performance.
