摘要:Low ionic conductivity and poor interfacial compatibility between lithium electrodes and Li7P3S11 sulfide solid electrolytes are the greatest challenges for all-solid state lithium-sulfur batteries. Herein, we introduce a hybrid solid electrolyte with Li7P3S11 being wrapped with polyethylene oxide-LiClO4 (PEO-LiClO4). As served as conductive bridge between Li7P3S11 particles, PEO-LiClO4 would provide Li+ transition paths between Li7P3S11 particles, thus successfully improve its ionic conductivity. Moreover, the polymer layer of PEO-LiClO4 can isolate lithium metal and Li7P3S11 solid electrolyte, suppressing the reaction between lithium electrode and Li7P3S11 electrolyte. Therefore, hybrid solid electrolyte Li7P3S11-PEO-LiClO4 shows excellent interfacial compatibility with lithium foil. Lithium-sulfur battery with the hybrid electrolyte Li7P3S11-PEO-LiClO4 exhibits much improved electrochemical performance with better cycling stability and higher Coulombic efficiency.
