High-temperature separators (HTSs) represent an effective strategy for addressing the safety issues of lithium-ion batteries (LIBs), while the electrochemical performance of batteries assembled with HTSs needs to be improved. Herein, a HTS containing the semi-interpenetrating network (sIPN) was constructed by in-situ polymerizing vinyl imidazole (VIm) in poly (aryl ether benzimidazole)(OPBI) for the first time. The sIPN separators exhibited excellent thermal stability, showing no significant shrinkage at 200° C, which …
