    • A polymeric solid electrolyte capable of conducting lithium ions which contains silylamide bonds in its polymer skeleton structure, for example, which is obtained by a method comprising subjecting a mixture of lithium silylamide and an organic compound having at least one carbon—carbon double bond to a polymerization in a dry atmosphere; and a lithium secondary cell using the polymeric solid electrolyte. The polymeric solid electrolyte is a “dry” polymeric solid electrolyte which contains counter ions forming lithium salts with lithium ions in its polymer skeleton structure and thus has a single ion electron conducting system wherein lithium ions alone are mobile ions, and hence has excellent conductivity, and further is easy to produce. The polymeric solid electrolyte can therefore be used for producing a novel lithium secondary cell which is an alternative for conventional lithium cells using an organic solvent and is safe and excellent in the capability of corresponding to a variety of shapes and has a high cell voltage.
    • 能够在其聚合物骨架结构中导电含有甲硅烷基酰胺键的锂离子的聚合物固体电解质,例如通过包括将具有至少一个碳 - 碳双键的锂甲硅烷基酰胺和有机化合物的混合物 在干燥气氛中聚合; 和使用聚合物固体电解质的锂二次电池。 聚合物固体电解质是一种“干”聚合物固体电解质,其包含在其聚合物骨架结构中与锂离子形成锂盐的反离子,因此具有单独的离子电子传导系统,其中单独的锂离子是移动离子,因此具有优异的导电性, 并且进一步易于生产。 因此,聚合物固体电解质可用于制造新的锂二次电池,其是使用有机溶剂的常规锂电池的替代方案,并且对于各种形状的能力安全且优异且具有高的电池电压。
