POLYMER SOLID ELECTROLYTE COMPOSITION MATERIAL

摘要

PURPOSE:To provide a polymer solid electrolyte composition material with high ion conductivity at the room temperature by combining specific trifunctional polyoxyalkylene glycerol and a benzalacetophenone compound. CONSTITUTION:An organic solid electrolyte is mainly constituted of an inorganic electrolyte and a cross-linked polymer obtained by photo-cross-linking a compound introduced with a bendalacetophenone compound expressed by the formula II or the formula III as a photo-functional group into the terminal hydroxyl group of trifunctional polyoxyalkylene glycerol expressed by the formula I, where (n) in the formula I is 20 or below, and R in the formula II and the formula III indicates hydrogen, alkyl, alkoxyne or a hydroxyl group.
