Heat-resistant poly (arylene ether nitriles) separator for high-safety lithium batteries via dual-functional modification

Abstract Herein, we report a dual-modified organic-inorganic separator as an alternative to polyolefin commercial for lithium metal batteries. This composite exhibits high thermal stability properties due the use of engineering plastic matrix poly (arylene ether nitriles) (PEN). The dual hydrophilic modification strategy also allows have ionic conductivity and low interfacial impedance. With this new separator, lithium-metal batteries charge/discharge capacity high-rate performance. Moreover, Li/Li symmetric cells display long-term phenomenon suppressing dendrite in
