THERMOSETTING ELECTROLYTE COMPOSITION FOR LITHIUM SECONDARY BATTERY GEL POLYMER ELECTROLYTE PREPARED THEREFROM AND LITHIUM SECONDARY BATTERY COMPRISING THE SAME

摘要

The present invention relates to a thermosetting electrolyte composition for a lithium secondary battery, a gel polymer electrolyte prepared therefrom and a lithium secondary battery comprising the same. The present invention relates to a thermosetting electrolyte composition for a lithium secondary battery, comprising LiPF_6 as a first lithium salt, a second lithium salt excluding LiPF_6, a non-aqueous organic solvent, and a polymer or oligomer including a unit represented by chemical formula 1. The present invention also relates to a gel polymer electrolyte prepared therefrom and a lithium secondary battery comprising the same.
