Dr. Wang Shuo, a young faculty member from the School of Materials Science and Engineering at Wuhan University of Technology (WUT), has recently made significant progress in the field of sulfide-based all-solid-state batteries through a collaborative effort with the team of Academician Ce-Wen Nan from Tsinghua University and Professor Mingxue Tang from the Center for High Pressure Science & Technology Advanced Research (HPSTAR). Their study, titled “Large-scale manufacturing sulfide superionic conductor for advancing all-solid-state batteries” was published in Matter, a Cell Press journal. The School of Materials Science and Engineering / State Key Laboratory of Advanced Technology for Materials Synthesis and Processing at WUT is listed as the primary corresponding affiliation.

This study presents a comprehensive approach from material design and process innovation to structural analysis and battery testing, demonstrating the potential of high-performance sulfide electrolytes for practical applications. It not only proposes superior material designs but also introduces an energy-efficient, high-yield manufacturing process, offering significant insights for the industrialization of solid-state batteries.

Compared with many sulfide systems still confined to laboratory research, the LPSCB (Li_5.5PS_4.5Cl_0.75Br_0.75) electrolyte developed in this study represents a significant step closer to practical deployment. Its high ionic conductivity, low activation energy, excellent interfacial stability, and kilogram-scale production make it a promising candidate for the industrialization of next-generation all-solid-state batteries. As synthesis techniques continue to improve and electrode compatibility is further refined, batteries based on this material are expected to become commercially viable in the near future.
