摘　　要：聚氧化乙烯 ( PEO)基电解质是研究最早的聚合物电解质体系 ,它在电池生产中已得到应用。 PEO基聚合物电解质主要分为聚合物 /盐型和凝胶型两大类 ,凝胶型聚合物电解质因具有较高的电导率而被认为是固态锂离子电池最有应用前景的电解质体系。对两种类型的聚合物电解质的研究进展作了较为详细的论述 ,在此基础上分析了 PEO基聚合物电解质中离子的传输机理。PEO基聚合物电解质中离子的运动能力与链的结构、离子浓度、温度、增塑剂等因素有关。Poly(ethylene oxide)-alkaline metal com pl ex as solid polymer electrolyte has been researched in the early days, and it ha s been used in the manufacture of batteries. Poly(ethylene oxide)-based electr olytes can be divided into two types: dry solid polymer electrolyte and gelled s olid polymer electrolyte. Gelled solid polymer electrolyte displays high conduct ivity, and it is considered as the prospective electrolyte for solid lithium ion battery. The research and development of poly(ethylene oxide)-based solid elec trolyte was reviewed, and the mechanism for ion transfer in the polymer electrol yte was analyzed. The ionic conductivity of PEO-based electrolyte is related to the structure of polymer chain, concentration of ion temperature and plasticize r.
