The present invention provides a thin film of non-protonic electrolyte and electrolyte-immobilized liquid-film conductor, easily produced into a thin film and to have a large area, securely holding the non-protonic electrolytic solution over a wide temperature range, and showing stability for extended periods and improved mechanical strength. They comprise a polyolefin film with a solvent-resistant polyolefin as the basic component, which is impregnated with the non-protonic electrolytic solution to immobilize it. The polyolefin composition for the film contains a terminal-modified polypropylene having, in the terminal chain, a functional group showing an affinity for the solvent for the electrolytic solution for the thin film of non-protonic electrolyte, and further contains an electron-conductive substance in addition to the terminal-modified polypropylene for the electrolyte-immobilized liquid-film conductor. As a result, the polyolefin film stably holds the solvent for the electrolytic solution. The present invention also provides a battery which uses the above thin film of non-protonic electrolyte and/or electrolyte-immobilized liquid-film conductor.
                            本发明提供了一种非质子电解质薄膜和电解质固定液膜导体,易于制成薄膜并具有较大面积,可在较宽的温度范围内牢固地保持非质子电解溶液,并显示出长时间的稳定性和较高的机械强度。它们包括一层聚烯烃薄膜,以耐溶剂聚烯烃为基本成分,浸渍在非质子电解溶液中使其固定。薄膜用聚烯烃组合物含有端链中具有与非质子电解质薄膜用电解溶液溶剂亲和性官能团的端改性聚
丙烯,除了端改性聚
丙烯外,还含有电子导电物质,用于电解质固定液膜导体。因此,聚烯烃薄膜能稳定地保持电解溶液的溶剂。本发明还提供了一种使用上述非质子电解质薄膜和/或电解质固定液膜导体的电池。
