제목 Nonflammable gel polymer electrolytes based on perfluoropolyether (PFPE) for lithium secondary batteries
초록 Gel polymer electrolytes based on perfluoropolyether (PFPE) network and PFPE plasticizer were firstly prepared and their properties including thermal properties, ionic conductivity, and cell performance were investigated. Free standing films could be obtained with 30 wt% of PFPE crosslinker content. The ionic conductivity and lithium transference number of the prepared gel polymer electrolytes at 60 oC were 1.72 x 10-5 S cm-1, and 0.53, respectively. The prepared gel polymer electrolytes were non-flammable, thermally stable, and electrochemically stable up to 5.0 V (vs. Li/Li+), therefore they were suitable for safety-ensured high-temperature lithium secondary batteries.
