A UV-CURED MULTI-COMPONENT POLYMER BLEND ELECTROLYTE, LITHIUM SECONDARY BATTERY AND THEIR FABRICATION METHOD

摘要

The present invetion relates to a UV-cured multi-component polymer blend electrolyte, lithium secondary battery and their fabrication method, wherein the UV -cured multi-component polymer blend electrolyte, comprises: A) function-I polymer obtained by curing ethyleneglycoldi-(meth)acrylate oligomer of formula 1 by UV irradiation, CH2=CR<1>COO(CH2CH2O)nCOCR<2>=CH2 (1) wherein,R<1> and R<2> are independently a hydrogen or methyl group, and n is an integer of 3-20;B) function-II polymer selected from the group consisting of PAN-based polymer, PMMA-based polymer and mixtures thereof; C) function-III polymer selected from the group consisting of PVdF- based polymer, PVC-based polymer and mixtures thereof; and D) organic electrolyte solution in which lithium salt is dissolved in a solvent.
