摘要: A new class of thin, safe and foldable solid composite electrolytes are produced by uploading 3-arm poly-(methoxy-poly(ethylene glycol) methacrylate) (3PEG) onto three different electrospun membranes, poly(vinylidene fluoride-co-hexafluoropropylene) (P(VdF-HFP)) membrane, 3PEG co-sprayed P(VdF-HFP) membrane (3PEG/PHP) polyethylene terephthalate (PET) named 3PEG@PHP, 3PEG@3PEG/PHP 3PEG@PET, respectively. The membranes serve as a skeleton to enhance the mechanical strength electrolytes, whereas filled in micropores matrix affords an ion transport carrier. Among these one based on PET exhibited high ionic conductivity 5.9 × 10−4 S cm−1 at 100 °C because it possessing lowest shrinkage rate with filling loading 3PEG. decomposition potential is above 4.5 V °C. Successful charge discharge cycling 3PEG@PET all state lithium battery have maintained initial capacity 137.6 mA h g−1 0.1C, which proves that they ideal candidates for rechargeable batteries.
