Synergistic Enhancement in Properties of Composite Solid Electrolytes via PAN and in-situ SiO2 for All-Solid-State Lithium Batteries

PAN and in situ -generated SiO 2 synergistically reduce the PEO crystallinity and promote ion transport. The composite electrolyte exhibits enhanced ion conductivity, interfacial stability, and stable cycling, with suppressed lithium dendrite growth.
