PURPOSE: To enable the extrusion of a thin film by adding a mixture of the specified elastomer copolymer and the specified aliphatic ether plasticizer of the polyethylene oxide to an electrolyte polymer. CONSTITUTION: A mixture is formed with SIS or SBS block elastomer copolymer represented by formula I (a and c are 40-80, b is 20-100, R shows H or an alkyl group having 1-7 carbon atoms such Qs CH3 and C2 H5 ) and an aliphatic ether plasticizer of polyethylene oxide derived from cetyl, stearyl, oleyl, or isohexadecyl alcohol. An additive containing the mixture is added to a polymer constituting an electrolyte for a lithium/polymer electrolyte battery. Thereby, extrusion of a thin film is made possible, and electrochemical characteristics of the battery is enhanced. |
