A zincophilic separator with directional alignment and pore hydrophilicity towards stable aqueous zinc metal batteries

A zincophilic PAN@Zn(OTF)2 (PZO) separator with an extremely thin thickness of 65.6 mu m is introduced. This separator with a low cost of 6.1 $ m-2, exhibiting excellent mechanical and wettability properties. The cell with the PZO separator exhibits impressive electrochemical performances both in symmetrical Zn||Zn cell and Zn||NVO full cell. A low-cost and excellent mechanical property zincophilic separator (PZO) is developed by incorporating a Zn(OTF)2 salt into the PAN nanofibers.
