All?Solid?State Lithium–Sulfur Batteries of High Cycling Stability and Rate Capability Enabled by a Self?Lithiated Sn?C Interlayer
A self?lithiated tin (Sn)?carbon (C) composite interlayer (LSCI) capable of enhancing electrochemical/structural stability and homogenizing lithium (Li)?ion transport across the Li/solid?state electrolyte (SSE) interfaces enables an all?solid?state lithium–sulfur battery (ASSLSBs) with high cycling stability and rate capability.All?solid?state lithium–sulfur batteries (ASSLSBs) have attracted intense interest due to their high theoretical energy density and intrinsic safety. However, constructing durable lithium (Li) metal anodes with high cycling efficiency in ASSLSBs remains challenging due to poor interface stability. Here, a compositionally stable, self?lithiated tin (Sn)?carbon (C) composite interlayer (LSCI) between Li anode and solid?state electrolyte (SSE), capable of homogenizing Li?ion transport across the interlayer, mitigating decomposition of SSE, and enhancing electrochemical/structural stability of interface, is developed for ASSLSBs. The LSCI?mediated Li metal anode enables stable Li plating/stripping over 7000 h without Li dendrite penetration. The ASSLSBs equipped with LSCI thus exhibit excellent cycling stability of over 300 cycles (capacity retention of ?80%) under low applied pressure (
