Abstract
A gel polymer electrolyte composition includes i) a compound acting as a monomer for forming gel polymer by polymerization and having at least two double bonds at an end thereof; ii) an electrolyte solvent containing carbonate and linear saturated ester; iii) an electrolyte salt; and iv) a polymerization initiator. A gel polymer electrolyte formed using the above composition has excellent mechanical strength and lithium ion conductivity. A secondary battery containing the gel polymer electrolyte has improved room/low temperature characteristics and rate capacity.
