The research focuses on solid-state electrolytes and interfacial regulation for high-performance batteries, encompassing oxide framework–based composite electrolytes via ultra-fast high-temperature sintering (UHS), cellulose-based electrolyte and separator systems, and dielectric-material-enabled regulation strategies. By constructing robust inorganic frameworks through UHS combined with in situ polymerization, continuous ion-conduction pathways and intimate interfacial contact are achieved. Cellulose-based systems leverage the tunable structure and coordination capability of natural polymers to develop mechanically robust and safe electrolyte/separator materials. In addition, high-dielectric-constant components are introduced to regulate local electric field distribution and ion solvation structures, thereby promoting salt dissociation and stabilizing electrode/electrolyte interfaces. Through the synergistic design of structure, interface, and transport properties, this research aims to simultaneously enhance ionic conductivity, interfacial stability, and mechanical strength, ultimately enabling the development of high-performance solid-state lithium metal batteries.
