In this paper, sulfide glass electrolyte powder with a nominal composition of (Li₂S)₆₀(SiS₂)₂₈(P₂S₅)₁₂ is hot pressed at a 330°C and 12 MPa into separator films using non‐woven fiberglass reinforcement. The reinforced separator films are 93% dense, bendable, and have an ionic conductivity of 0.7 mS/cm at room temperature. When integrated into hybrid Li‐S coin cells with liquid electrolyte, these reinforced glass separators blocked the parasitic polysulfide shuttle sufficiently to enable reversible cycling without LiNO₃ co‐salt. Furthermore, the scalability of the reinforced glass separator technology is demonstrated by assembling and testing a hybrid single‐layer pouch cell.

混合式Li‐S袋式电池，带有增强的硫化物玻璃固态电解质膜隔板

本文将标称成分为（Li ₂ S）₆₀（SiS ₂）₂₈（P ₂ S ₅）_12的硫化物玻璃电解质粉末在330°C和12 MPa下使用无纺玻璃纤维热压成隔膜加强。增强隔膜的密度为93％，可弯曲，在室温下的离子电导率为0.7 mS / cm。当这些增强的玻璃隔板与带有液体电解质的混合Li-S币形电池集成在一起时，它们可以充分阻挡寄生的多硫化物穿梭，而无需LiNO ₃即可实现可逆循环盐此外，通过组装和测试混合单层袋式电池，展示了强化玻璃隔板技术的可扩展性。
