The development of high-performance separators is urgently needed to improve the safety and electrochemical performance high-energy-density lithium metal batteries (LMB). Poly (ether ether ketone) (PEEK) an ideal separator candidate due its high chemical resistance excellent thermal stability. However, processing PEEK for with proper porous structure rather challenging. Beyond conventional sulfonation process PEEK, here, a reversible modification strategy exploited fabricate heat-resistant sophisticated hierarchical pore architecture. lyophilic including dense surface layers, middle layers horizontally aligned arrays, honeycomb-structured bottom enable fast ion transport uniform Li+ flux, realizing dendrite-free characteristics during deposition process. Hence, assembled LiFePO4||Li battery delivers remarkable capacity 103.6 mAh·g-1 after 1000 cycles at 3 C, offers more than two times longer cycle life that other PEEK-based separators. Even 70 °C, retention rate 84.2% achieved 200 cycles, ensuring in high-temperature environments. Different from commonly used functional separators, approach reported herein exhibits fundamental advance manufacturing future high-safety LMBs.
