Gel polymer electrolyte with heterostructure and quasi-solid-state lithium metal battery

The invention relates to a gel polymer electrolyte with a heterostructure and a lithium metal quasi-solid-state battery, the electrolyte comprises a polymer electrolyte membrane and an organic electrolyte, the polymer electrolyte membrane comprises a polymer matrix, a metal organic framework ZIF-8 material and alumina; the organic electrolyte comprises an organic solvent and a lithium salt. The electrolyte can overcome the safety problem that a traditional liquid electrolyte is prone to leakage and the defect that an all-solid electrolyte is poor in interface compatibility, and has excellent mechanical performance, ionic conductivity and ionic transference number. The invention also relates to a lithium metal battery assembled by using the gel polymer electrolyte with the heterostructure, the growth of lithium dendrites can be effectively inhibited, and excellent cycle stability is realized. 本发明涉及一种异质结构的凝胶聚合物电解质和锂金属准固态电池，该电解质组成包括聚合物电解质膜和有机电解液，所述聚合物电解质膜包括聚合物基体、金属有机框架ZIF-8材料和氧化铝；所述有机电解液包括有机溶剂和锂盐。该电解质能够克服传统液态电解质
