中文摘要：
锂离子导电膜是锂离子电池的核心材料，研究了以可溶胀聚合物多孔膜作为骨架、在其孔道内填充凝胶结构而制备的锂离子导电膜。首先采用溶液相转化法制备了聚（偏氟乙烯-六氟丙烯）（PVDF—HFP）多孔膜，然后将多孔膜浸入含有锂盐、聚乙二醇二丙烯酸酯（PEGDA）和过氧化苯甲酰的碳酸酯溶液吸收电解液，再加热引发PEGDA中双键交联得到具有多孔骨架和交联PEG的锂离子凝胶聚合物电解质膜（Li—GPEM）。失重、力学和及电化学性质分析表明，所制备的Li—GPEM的电导率为2．25mS／cm，综合性能优于PVDF-HFP多孔膜吸附液态锂盐溶液的体系和共混凝胶膜体系。
英文摘要：
Lithium ion conducting membranes are the key materials for lithium batteries. The lithium ion conducting gel polymer electrolyte membranes （Li-GPEMs） containing PVDF-HFP porous matrix filled with crosslinked PEG network are presented and prepared via the following route. The porous membranes of PVDF- HFP are obtained by typical phase inversion process. By immersing porous PVDF-HFP membrane in liquid electrolyte containing PEGDA at 25℃ to absorb the liquid electrolyte,and then thermal crosslinking at 60℃,the Li- GPEMs are fabricated successfully. The measurements in weight loss, mechanics and electrochemistry reveal that the obtained Li-GPEMs have the better overall performances than the liquid or blend gel system while being used as conduction medium in lithium batteries. The highest conductivity of Li-GPEM can reach as high as 2.25 × 10^-3S/cm.
