China FAW Group, together with Dongfang University of Science and Technology, reported a technical breakthrough enabling low‑pressure operation of sulfide all‑solid‑state batteries. The result, published as "Ionic elastomer interface enables low‑pressure, high‑stability solid‑state batteries" in Advanced Energy Materials, demonstrates an ionic elastomer interface that achieves low‑pressure, high‑stability performance. Researchers describe the work as a milestone in core technology for practicalizing sulfide all‑solid‑state batteries and a key step toward their industrialization in China.
