Polymer electrolyte composite containing the amine acrylate compounds and lithium-polymer secondary battery using the same

摘要

PURPOSE: A composition for gel polymer electrolyte is provided to prevent the short circuit of a positive electrode and a negative electrode by introducing an amine acrylate compound, thereby improving ion conductivity and electrochemical stability at room temperature. CONSTITUTION: A composition for gel polymer electrolyte contains an amine acrylate compound in chemical formula 1 as a crosslinking agent. In chemical formula 1, m and n is respectively and independently an integer from 0-3, m+n is 3, a composition for a polymer electrolyte contains a crosslinking agent, liquid electrolyte, and cure type initiator. 2-10 weight% of the crosslinking agent, 88-97.9 weight% of the liquid electrolyte, 0.01-2 weight% of the cure type initiator are comprised.
