Low‐Pressure All‐Solid‐State Lithium–Sulfur Batteries: Challenges and Design Principles
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...
