Transition metal sulfides have attracted particular interests owing to their extremely higher specific capacity and more compatible with sulfide electrolyte than lithium transition-metal oxide for all-solid-state lithium batteries. FeS nanosheets with thickness of 10 tun are synthesized by a poly (vinyl alcohol)-assisted precipitation method and further successfully employed in Li/70%Li2S-29%P2S5-1%P2O5/Li10GeF2S12/FeS all-solid-state lithium batteries. The obtained all-solid-state lithium batteries show reversible discharge capacity of 550 mAh g(-1) after 50 cycles at current density of 0.1 A g(-1) and exhibit superior rate performances.
