MANUFACTURE OF SOLID POLYMER ELECTROLYTE BATTERY, SOLID POLYMER ELECTROLYTE BATTERY, AND NONAQUEOUS SOLUTION ELECTROLYTE FOR BATTERY

摘要

PROBLEM TO BE SOLVED: To enhance the extraction efficiency of a plasticizer and provide a battery with no adverse effect caused by the remaining extracting agent by using the specified silicone compound as an extracting agent of the plasticizer in the manufacture of a solid polymer electrolyte battery using a nonaqueous solution electrolyte by jointly using the plasticizer. SOLUTION: A solid polymer electrolyte battery is manufactured in such a process that a polymer composition containing a plasticizer and a polymer compound is formed in layer, the plasticizer is extracted with at least one low molecular weight organic silicone compound selected from a chain organic silicone compound represented by formula I (R is the same or different, non- substituted or substituted monovalent organic group, m is an integer of 0-7.) and a cyclic organic silicone compound represented by formula II (R is the same meaning as R in formula I, n is an integer of 3-10.). A nonaqueous solution electrolyte is impregnated in the polymer compound layer from which the plasticizer is extracted to form a solid polymer electrolyte layer.
