Stabilizing Interface between Li(2)S-P(2)S(5) Glass-Ceramic Electrolyte and Ether Electrolyte by Tuning Solvation Reaction

Résumé

Using solid-liquid hybrid electrolytes is an effective strategy to overcome the large solid/solid interfacial resistance in all-solid-state batteries and the safety problems in liquid batteries. The properties of the solid/liquid electrolyte interphase layer (SLEI) are essential for the performance of solid-liquid hybrid electrolytes. In this work, the solvation reactions between Li(2)S-P(2)S(5) glass-ceramic solid electrolytes (SEs) and ether electrolytes were studied, and their influence on the SLEI was examined. Although 1,2-dimethoxyethane (DME) reacted with the Li(2)S-P(2)S(5) glass-ceramic SE to form a dense SLEI, 1,3-dioxolane (DOL) severely corroded the SE, resulting in a loose SLEI. Consequently, a stable SLEI formed with DME. Using a combination of the Li(2)S-P(2)S(5) glass-ceramic SE and the DME-based liquid electrolyte (LE), stable lithium plating/stripping cycles over 1000 h and a hybrid Li-S battery that retained a specific capacity of 730 mAh g(-1) after 200 cycles were demonstrated. The knowledge of the reactions between the sulfide electrolytes and the organic LEs is instructive for the design of stable sulfide-liquid hybrid electrolytes for advanced batteries.
