Lithium ion conducting polymer electrolyte

Abstract

Abstract PURPOSE:To obtain good lithium ion conductivity in a solid shape at the room temperature by using the preset cross-linked polymer for an organic polymer. CONSTITUTION:A battery 1 is provided with a positive electrode current collecting plate 1, a negative electrode current collecting plate 2, a positive electrode 4, a space 5, a negative electrode 6, and a separator 7. The separator 7 is formed with a lithium ion conducting polymer electrolyte made of a composite body of lithium salt and an organic polymer, a cross-linked polymer cross- linked with polysiloxane-graft polyether indicated by the formula I is used for the organic polymer. In the formula I, R1 is hydrogen, a low-level alkyl group, R2 is hydrogen or a low-level alkyl group, (x)=0.1-1.0, (y)=0.1-1.0, (m)=1-200, (n)=3-40.
