Development of ionically conducting inorganic binders for solid-state batteries

粘合剂通过连接活性材料和导电添加剂并促进电极材料在所需基板上的涂层起着至关重要的作用，从而使电池的柔性制造成为可能。此外，它们有助于缓冲电极材料的体积变化，并提高其循环稳定性。聚偏氟乙烯基粘合剂尽管成本高、不环保、能源效率低，但应用广泛。近年来引入了离子导电无机粘结剂（ICIBs）来取代聚偏氟乙烯基粘结剂。这些icib不仅具有离子导电性，而且具有水处理性、化学相容性、环保、低成本、热稳定性（>1000℃）、无排放，而且重要的是，使用安全。本研究的重点是进一步发展这些icib，特别是它们的离子电导率，验证它们在固态电池中的性能，并将开发新的icib。

Binders play a vital role by interconnecting active materials and conductive additives and facilitating the coating of electrode materials on the desired substrates, thus enabling the flexible fabrication of batteries. Further, they aid in buffering volume changes in electrode materials and enhance their cycling stability. Polyvinylidene fluoride-based binders are employed widely, despite their high cost, non-eco-friendliness, and energy inefficiency. Recently ionically conducting inorganic binders (ICIBs) were introduced to replace polyvinylidene fluoride-based binders. These ICIBs are not only ionically conducting but also water processable, chemically compatible, eco-friendly, low-cost, thermally stable (>1000C), emission-free, and, importantly, safe to use. This study focuses on the further development of these ICIBs, particularly their ionic conductivity, validating their performance in solid-state batteries, and new ICIBs will be developed.
