Room-temperature Li⁺ conductors have been intensively revisited to develop high-safety solid-state batteries. While promising inorganic Li⁺ solid-state electrolytes (SSEs) with competitive ionic conductivity have been demonstrated, their practical applications are still hindered by manufacturing technology, cost constraints, and internal battery interfaces. Advances in the design and synthesis of periodic frameworks over the past decade have created a new platform for designing SSEs. These porous crystalline frameworks feature open channels that can be tailored into ion-hopping sites and guest-accessible voids, both essential for SSE construction. Framework-based SSEs uniquely merge the advantages of inorganic crystal-like ordered structures and the design flexibility of organic molecules, distinguishing them significantly from traditional inorganic or organic SSEs. Enhancing ionic conduction and exploring potential applications are two critical factors driving the rapid advancement of framework-based SSEs.

作为离子导电固态电解质的多孔晶体框架

室温 Li⁺ 导体已被深入重新审视，以开发高安全性的固态电池。虽然已经证明了具有竞争性离子电导率的有前途的无机 Li⁺ 固态电解质（SSE），但它们的实际应用仍然受到制造技术、成本限制和内部电池接口的阻碍。过去十年中周期性框架设计和综合的进步为设计 SSE 创造了一个新平台。这些多孔晶体框架具有开放通道，可以定制成离子跳跃位点和访客可接近的空隙，这两者都对 SSE 构建至关重要。基于框架的 SSE 独特地融合了无机晶体状有序结构的优势和有机分子的设计灵活性，使其与传统的无机或有机 SSE 明显不同。增强离子传导和探索潜在应用是推动基于框架的 SSE 快速发展的两个关键因素。
