제목 | Electrodeposited Thin Li Metal Anodes Protected via Electroless In Plating For All-Solid-State Batteries |
초록 | Lithiummetal is a promising anode for next-generation all-solid-state Li metal batteries(ASLMBs) due to its high theoretical capacity (3,860 mA h g-1) and lowestelectrochemical potential (-3.04 V vs. SHE). Sulfide-based solid electrolytes(SEs) attract much attention thanks to their high ionic conductivities as high asthose of liquid electrolytes and deformable mechanical properties. However, ASLMBs using sulfide SEs suffer destructive electrochemical evolution owing to the unstableinterfaces between Li metal and SEs, which originates from i) the lowelectrochemical voltage windows of sulfide-based SEs and ii) the penetratinggrowth of Li metal via grain boundaries or defects of SEs. Herein, wereport on interfacial evolution between thin Li metal anodes and SEs for ASLMBs.The interfacial stability improved by the In/LixIn protective layerswill be presented along with operando electrochemical pressiometry analysisresults. |
