摘　　要：凝胶聚合物电解质是解决液态锂离子电池安全性问题的关键。聚甲基丙烯酸甲酯(PMMA)与碳酸酯类有机溶剂具有很强的相互作用,因而吸液能力强,是理想的凝胶聚合物电解质骨架组分。综述了以PMMA为主要组分的几种凝胶聚合物骨架的制备方法,包括聚合、交联、浇铸涂膜法、相转移法、共混、无机纳米粒子掺杂等,并讨论了这些聚合物骨架在凝胶聚合物电解质的应用中所起到的作用及导电模型。Gel polymer electrolyte plays a key role in solving safety problems for Li-ion batteries that uses liquid electrolytes. Polymethyl methacrylate （PMMA） has intensive interaction with organic solvents such as carbonate and is good at absorbing electrolyte. Thus it is one of the most useful components of the matrix for gel polymer electrolyte. In this paper, the recent research progresses on the preparation of different gel polymer matrixes which were based on PMMA were reviewed, including polymerization, cross-linking, casting fihn technique, phase inversion, blending, doping inorganic nano-fillers, etc. The roles that these matrixes played in the performance of gel polymer electrolytes and the conductive models were also discussed.
