| Abstract: | We report the fast discharge–charge cycle of micro-sized FePS3 electrode particles in all-solid-state batteries (ASSBs) using sulfide electrolytes at 80°C. At a current density of 2.04 mA cm−2, corresponding to approximately 1 C, the capacity of the FePS3 electrodes reached ∼180 mAh g−1 without any electron or lithium-ion conductive additives. Galvanostatic intermittent titration technique (GITT) measurements showed a stable diffusion path of FePS3 represented by the product of the diffusion coefficient and square of the surface area. These electrochemical properties were compared with those of FeS, whose capacity was lower because of its unstable diffusion path. |
