✦ Synopsis

The effect of the heat treatment on the tensile properties and the dynamic moduli of polymer matrix films and polymer electrolytes were studied to further increase the mechanical properties. The crosslinking of latex particles brought about their improvements by heating. We have fabricated the polymer electrolyte with a tensile strength of 3.0 MPa, together with a conductivity above 1 mS/cm for application to a lithium secondary battery. This polymer electrolyte had the highest tensile strength among the known gel polymer electrolytes having conductivity over 1 mS/cm, although mechanical properties of plasticized polymer electrolytes have rarely been reported.
