Major Contributions
1. Interpenetrating polymer network (IPN) electrolytes combining PEO and PVdF-type networks are designed to provide interconnected Li⁺ transport pathways, achieving high ionic conductivity and Li⁺ transference number in solid-state lithium batteries at moderate temperatures.
2. The IPN architecture regulates local Li⁺ flux distribution at the Li-metal anode interface, enabling uniform Li deposition and suppressing dendrite growth for improved Coulombic efficiency and cycling stability.
3. Li||IPN electrolyte||cathode cells exhibit enhanced rate capability and long-term cycling performance, demonstrating the effectiveness of network polymer design for addressing both conductivity and interfacial challenges in practical SSLBs.
