  "abstract": "Gel polymer electrolytes are attractive quasi-solid electrolyte systems that combine the high ionic mobility and electrode wetting of liquid electrolytes with the dimensional stability and reduced leakage of polymer networks. Their value for high-performance lithium-ion batteries is increasingly determined not only by bulk ionic conductivity, but also by Li+ selectivity, solvent retention, mechanical integrity, electrochemical stability, and the ability to form stable interfaces with high-voltage cathodes and practical graphite and Si-containing anodes. This review critically summarizes recent progress in GPEs through a structure, transport, interface-performance framework, with particular emphasis on developments reported in recent years while retaining foundational studies that established the field. Representative polymer hosts, including PVDF/PVDF-HFP, PEO, PAN, PMMA and methacrylate networks, cellulose-derived matrices, and emerging functional polymers, are compared according to their molecular functionality and practical limitations. Major performance-enhancement strategies-including blending, crosslinking, inorganic or nanostructured fillers, functional additives, nonflammable components, self-healing chemistries, and in situ polymerization-are then evaluated in terms of how they regulate ion transport, interphase chemistry, mechanical behavior, thermal safety, and manufacturability. Recent demonstrations in NCM/graphite and NCM/Si graphite pouch cells show that conformal in situ gelation, LiF-rich interphases, adaptive network mechanics, and low-reactivity liquid phases can translate materials-level improvements into high-rate cycling, long life, and improved abuse tolerance. Remaining challenges include conductivity, mechanical strength, high-voltage oxidation and wide-temperature operation. Future GPE development will therefore require integrated molecular, interfacial, and cell-level design rather than optimization of isolated membrane properties.",
