| description | To provide polyimide which can prevent corrosion by sulfide and satisfy various characteristics under cell operating environments even in the case where it applies to components of all solid type secondary batteries using a sulfide-based solid electrolyte containing a sulfur atom.SOLUTION: There is provided a polyimide used in the presence of a sulfide-based solid electrolyte containing a sulfur atom, wherein the polyimide is composed of a repeating unit comprising a structural unit derived from tetracarboxylic dianhydride and a structural unit derived from a diamine, and contains sulfur atoms in an amount of 10 mol% to 200 mol% in the repeating unit per mole.SELECTED DRAWING: None
【課題】硫黄原子を含む硫化物系固体電解質を用いた全固体二次電池の構成材料に適用する場合においても、硫化物による腐食を防止することができるとともに、電池使用環境下における諸特性も満足できるポリイミドを提供する。【解決手段】硫黄原子を含む硫化物系固体電解質の存在下で使用されるポリイミドであって、テトラカルボン酸二無水物に由来する構造単位と、ジアミンに由来する構造単位とからなる繰り返し単位から構成され、１モル当たりの該繰り返し単位中に硫黄原子を１０モル％～２００モル％含有することを特徴とするポリイミド。【選択図】なし |
