Pentafluoro(phenoxy)cyclotriphosphazene Stabilizes Electrode/Electrolyte Interfaces for Sodium‐Ion Pouch Cells of 145 Wh Kg −1
Tongji University · Huazhong University of Science and Technology
Abstract
Abstract Sodium‐ion batteries are competitive candidates for large‐scale energy storage batteries due to the abundant sodium resource. However, the electrode interface in the conventional electrolyte is unstable, deteriorating the cycle life of the cells. Introducing functional electrolyte additives can generate stable electrode interfaces. Here, pentafluoro(phenoxy)cyclotriphosphazene (FPPN) serves as a functional electrolyte additive to stabilize the interfaces of the layered oxide cathode and the hard carbon anode. The fluorine substituting groups and the π–π conjugated ─ PN ─ structure decrease the lowest unoccupied molecular orbital and increase the highest occupied molecular orbital of FPPN,…
