High‐Areal‐Capacity Sulfur Cathode Enabled by Dual‐Phase Electrolyte for Sulfide‐Based All‐Solid‐State Batteries

Advanced Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 8, 2025

Abstract All‐solid‐state lithium–sulfur batteries (ASSLSBs) incorporating sulfide‐based superionic conductors offer high safety and energy density are cost‐efficient. However, the effective utilization of sulfur is challenging due to difficulties in forming an intimate triple‐phase interface between electronic conductors, ionic sulfur. In this study, high‐performance ASSLSBs achieved through a simple two‐step mixing method that combines 1) high‐energy ball milling 2) mild sulfur/carbon composite with Li 6 PS 5 Cl (LPSCl). This approach reduces particle size, enhances uniformity, activates redox reaction LPSCl while preserving its conductivity, ultimately creating well‐distributed conduction pathways thick electrodes. During milling, catenation leads formation inorganic Li‐ion‐conducting species, improving contact Moreover, S–S bridging cleavage reactions oxidatively decomposed contribute reversibly additional capacity within operating voltage range. Consequently, optimal ASSLSB demonstrated areal 10.1 mAh cm −2 , retaining 92.0% initial after 150 cycles at 30 °C. cathode design further extendable other sulfur‐based cathodes dry electrode fabrication, offering viable pathway toward practical ASSLSBs.
