摘　　要：对新一代锂离子电池.特别是动力型电池用微孔型聚合物电解质膜材料的制备方法以及几类典型的聚合物电解质膜的特点进行了归纳和总结;比较了这一领域里萃取法、倒相法和直接造孔法的技术与工艺特点;用材料在实际电池中的机械强度、吸液率、耐高温性能、导电性能和电化学窗口宽度等指标考察了3种主要类型——单相型、两相型和复合型微孔聚合物电解质的各自优势与缺点;对微孔聚合物电解质的研制前景和开发趋势进行了展望。The preparation methods of micro-porous polymer electrolyte （MPE）membrane,which will be used for the next generation Li-ion secondary batteries especially for the power batteries, are summarized in this paper. Meanwhile the characteristics of a few typical MPE membranes are introduced as well. The techinical characteristics of extraction, phase transfer and direct pore-making methods are compared in detail. The advantages and disadvantages of three main types of MPE,single-phase,dual-phase and composite are reviewed on the base of a few important aspects, such as mechanical strength, absorbing ability for electrolyte, durability to high temperature, electric conductivity and electrochemical window width of the MPE showed in real batteries or electrochemical systems. Finally, the reseatch and develop trend and the prospect of micro-porous polymer electrolyte are forecasted in the Li-polymer power battery area.
