With the rapid development of lithium-ion batteries (LIBs), safety issues are the greatest obstacles that restrict their large scale-applications, especially for the high-energy-density electric vehicle and aviation industry. Separators play a crucial role in ensuring the safety of LIBs. However, due to their poor thermal stability, commercial polyolefin-based separators such as polyethylene (PE) still possess serious safety risks under abuse conditions. To address these challenges, a novel type of binder-free, thin ceramic-coated separator with superior safety characteristics is demonstrated in this research.
