Abstract AITranslate

A series of stretchable single-ion polymer electrolytes (SIPEs) based on Pluronic and 2-acrylamido-2-methylpropane sulfonic lithium (AMPS) are presented. Owing to the microphase separation of the soft segment and hard segment, this SIPE family exhibits high stretchability in which SIPE-2 can be stretched up to 840% with a fracture strength of 7.40 MPa. High Li+ content (2.06 wt %) is rationally incorporated via covalently grafting AMPS segments onto the polymer backbone, and therefore, these quasi-solid-state SIPEs delivers a considerable ionic conductivity of 1.10 × 10–4 S cm–1 at 65 °C, a wide electrochemical stability window (>5.0 V), and a high lithium transfer number (tLi+ > 0.93). Consequently, the stretchable and highly conductive single-ion polymer electrolytes show great potential for stretchable and flexible batteries.
