A series of flexible and highly conductive quasi-solid single-ion polymer electrolytes (abbreviated as PU-TFMSI) based on lithium sulfonimide are presented. Owing to the crosslinked structure with three types of segments (hard segment, soft segment and Li rich segment), PU-TFMSI displays a stretchability of 1350% and toughness of 13.6 MJ m-3. These PU-TFMSI single-ion electrolytes deliver high ionic conductivity over 1.3 x 10-4 S cm-1 at ambient temperature, a wide electrochem. stability window (up to 5.0 V vs Li+/Li), a high lithium transfer number (LTN 鈭?0.9), and good compatibility with electrodes. The LiFePO4/PU-TFMSI-2/Li coin cell exhibits stable cycling with an average Coulombic efficiency of 99.58% and superior rate performance. Furthermore, the LiFePO4//Li soft pouch cell with PU-TFMSI-2 single-ion electrolyte maintains functionality under bending. The flexible single-ion polymer electrolytes designed in this study have the potential to be applied in flexible devices and stretchable batteries.
