本文介绍了固体聚合物电解质在全固体电池方面的应用及其发展,叙述了新型固体聚合物电解质——亚甲氧基连接的聚氧化乙烯的研究工作。和聚氧化乙烯-盐电解质相比,亚甲氧基连接的聚氧化乙烯经氟甲基磺酸锂掺杂后的电导率在室温下提高3个数量级。 This paper introduces the application and development of solid polymer electrolytes in all-solid-state cells and describes the research work on the new solid polymer electrolyte-methyleneoxy-linked polyethylene oxide. The conductivity of methyleneoxy-linked polyoxyethylene doped with lithium fluoromethanesulfonate was increased by 3 orders of magnitude at room temperature compared to that of polyethylene oxide-salt electrolyte.
