主 题：all-solid-state lithium batteries infiltration ionic transport iron sulfide sulfide solid electrolyte
摘 要：All-solid-state lithium batteries(ASSLBs)based on sulfide solid electrolytes(SEs)are one of the most promising strategies for next-generation energy storage systems and electronic ***,the poor chemical/electrochemical stability of sulfide SEs with oxide cathode materials and high interfacial impedance,particularly due to physical contact failure,are the major limiting factors to the development of sulfide SEs in ***,the composite cathode of MOF-derived Fe_(7)S_(8)@C and Li_(6)PS_(5)Br fabricated by an infiltration method(IN-Fe_(7)S_(8))with dissoluble sulfide electrolyte(dissoluble SE)is *** SE can easily infiltrate the porous sheet-type Fe_(7)S_(8)@C cathode to homogeneously contact with Fe_(7)S_(8)nanoparticles that are embedded in the surrounding carbon matrixes and form a fast ionic transport *** from applying dissoluble SE and Fe_(7)S_(8)@C,the IN-Fe_(7)S_(8)-based cells displayed a reversible capacity of 510 mAh g^(-1)after 180 cycles at 0.045 mA cm^(-2)at 30℃.This work demonstrates a novel and practical method for the development of high-performance all-sulfide-based solid state batteries.
