Abstract
En 中文
• A low-cost, scalable zwitterionic diol chain-extender: suppresses crystallinity, anchors TFSI-, creates Li+ hopping sites. • The resulting polyurethane SPE gives ionic conductivity 1.6 × 10-4 S cm-1 at 60 °C and Li+ transference number 0.65. • Sulfonate-rich hard segments eliminate insulating domains, enabling Li+ transport along polymer backbone. • Lithium metal cells using the targeted SPE exhibit remarkable electrochemical performances.
