摘要
聚合物电解质具有负极腐蚀小、安全、易加工等优点,在镍氢电池中具有较高的应用价值,但综合性能仍未达到实用要求,改性是提高其性能的主要手段。从基体结构的改性、掺加无机填料、碱性成分的选择等方面综述了聚合物电解质的改性机理及研究进展,并对各改性方法进行了分析比较,同时展望了聚合物Ni/MH电池的应用前景。
Polymer electrolyte has great potential for application in Ni/MH battery due to its particular advan tages, such as low corrosion of anode materials, high safety, easy processing, etc. Modification is the main means to improve its comprehensive properties. The effective ways for the performance improvement of polymer electrolyte, i. e. , changing the molecular structures of polymer, applying nano-composite system and choosing new basic components are reviewed. Advantages and disadvantages of each modification method are also analyzed and compared. In addition, the application prospects of polymer Ni/MH batteries are discussed.
