Metal sulfides are promising sulfur electrocatalysts for lithium-sulfur (Li-S) batteries, yet their rational design is limited by an incomplete understanding of interfacial sulfur redox processes. Here, we reveal a vacancy-mediated sulfur-exchange mechanism that accelerates sulfur redox kinetics. Using Bi2S3 as a model...

ABSTRACT The escalating volume of decommissioned lithium cobalt oxide (LCO) batteries necessitates recycling strategies capable of adding value by transforming spent cathodes into high‐performance materials. While eutectic molten salt systems have emerged as a promising liquid–solid medium for direct regeneration, the...

All‐solid‐state lithium–sulfur batteries (ASSLSBs) are promising for high‐energy and safe energy storage, yet their practical operation remains constrained by the reliance on external stack pressure (usually > 80 MPa, even exceeding 120 MPa). While pressure can improve solid–solid contact, it primarily acts as a comp...
