Abstract
A solid polymer electrolyte includes a matrix prepared by subjecting an alkoxysilane compound having a urethane bond represented by Structural Formula 1 below and an alkoxysilane compound represented by Structural Formula 2 below to a sol-gel reaction; and a lithium salt dispersed in the matrix, and The solid polymer electrolyte composition is configured such that silsesquioxane is linked to a polycarbonate diol-based polymer chain having a urethane bond. The solid polymer electrolyte exhibits superior compatibility, stability, flexibility, mechanical properties and ionic conductivity.
