Solid polymer electrolyte, battery and solid-state electric double layer capacitor using the same as well as processes for the manufacture thereof
 A solid polymer electrolyte comprising a composite of (a) a polymeric component which comprises (i) a polymer obtained from at least one compound represented by general formula (IA), (IIA) and/or (IIIA) as described in the specification; or (ii) a polymer obtained from at least one compound having alcoholic hydroxyl groups wherein at least one hydrogen atom of said alcoholic hydroxyl groups is replaced by a unit represented by general formula (X) or (XI) as described in the specification, and (b) at least one electrolyte salt, which has a high ionic conductivity and can be made into a thin film. The present invention is also directed to an electrode comprising the solid polymer electrolyte and an electroactive substance or polarizable material; as well as a process for manufacturing the same. In addition, the present invention is directed to a primary an secondary battery having the solid polymer electrolyte, as well as a process for manufacturing the same. The battery of the present invention has a high capacity, high current density, and, in the case of a secondary battery, has good cyclability. Finally, the present invention is directed to a solid-state electric double layer capacitor comprising the solid polymer electrolyte, as well as a process for manufacturing the same. The electric double layer capacitor has a high output voltage and a large take-out current.
