Composition of Gel-Type Polymer Electrolytes Comprising Vinylidenefluoride and Acrylate Polymers and Process for Preparing the Same

摘要

The present invention relates to a polymer electrolyte composition is prepared by adding an organic solvent, lithium salt and the inorganic polymer and an acrylate-based polymer of vinylidene fluoride series. The gel polymer electrolyte prepared according to the present invention, was compared to the gel polymer electrolyte composed of only a polymer of conventional vinylidene fluoride series of, the ion conductive property excellent in a wide temperature range and to improve significantly the interface stability. Thus, the gel polymer electrolyte prepared in the present invention may be useful as a material for the lithium polymer secondary battery, a polymer electrolyte.
