Abstract
The present invention relates to a polymer electrolyte for a secondary battery and a lithium secondary battery comprising the same, and particularly, to a polymer electrolyte for a secondary battery, in which mechanical properties, ionic conductivity, and electrical conductivity are improved by comprising a polymer and an electron-acceptor having at least one double bond, as a dopant, and a lithium secondary battery in which electrochemical stability at high temperature and high voltage is enhanced by comprising the polymer electrolyte.
