This study reports an improved SPE architecture consisting of a three-dimensional (3D) polyacrylonitrile (PAN)–Li6.4La3Zr1.4Ta0.6O12 (LLZTO) fibrous skeleton infused with a polymer electrolyte ionic liquid (PIL), which promotes lithium-salt dissociation, accelerates Li+ transport, and enhances mechanical strength. The resulting SPE achieves an ionic conductivity of up to 0.51 mS cm−1. Li|Li symmetric cells using a 40-µm-thick SPE cycle stably for 2500 h at 0.2 mA cm−2 with a low overpotential of 30 mV. In Li|LiFePO4 (LFP) full cells, the electrolyte enables 86.8% capacity retention after 1000 cycles at 0.5 C and maintains stable operation at 130 °C. Flexible pouch-cell tests further confirm improved safety and durability under harsh conditions, highlighting the potential of this SPE design for high-voltage lithium metal batteries.","lang":"eng"}],"OA_type":"hybrid","date_updated":"2026-10-06T11:57:17Z","supplementarymaterial":"yes","language":[{"iso":"eng"}],"project":[{"name":"HighTE: The Werner Siemens Laboratory for the High Throughput Discovery of Semiconductors for Waste Heat Recovery","_id":"9B8F7476-BA93-11EA-9121-9846C619BF3A"}],"year":"2026","type":"journal_article","publisher":"Springer","PlanS_conform":"1"}]
