ABSTRACT:
A stable ion-conductive polymer electrolyte having a sufficiently high ionic conductivity, which will not be decreased during a long-term storing at a high temperature, and being free from any physical change such as crack, contraction and dissolution, is disclosed. It comprises: at least one polyol selected from the group consisting of an adduct composed of sorbitol and polyethylene oxide and an adduct composed of tetramethylol methane and polyethylene oxide, at least one ammonium salt or morpholinium salt, and at least one organic solvent.
