Ultrathin PTFE-Supported Composite Polymer Electrolyte Enabled by Metal-Organic Framework-Assisted Dual-Salt Regulation for Solid-State Lithium Metal Batteries.
Developing safe and high-energy solid-state lithium metal batteries (LMBs) remains challenging due to the need to simultaneously achieve ultrathin electrolyte membranes, fast ion transport, and mechanical robustness. Herein, we report a scalable 19 μm composite electrolyte based on a porous PTFE scaffold, a PEO/LiTFSI...
