Abstract:Polymeric membranes obtained much attention for decades owing to low cost, ease of process, and operation for battery separators, water purification, medical, etc., especially for the preparation of portable device materials. In this paper, we designed a membrane with polysulfone (PSF) grafted anthraquinone-hydroanthraquinone, namely the PSFAQ membrane. Various characterization (such as field emission scanning electron microscopy, transmission electron microscopy, etc.) and battery performance (such as galvanostatic charge/discharge test, cyclic voltammetry, etc.) indicated that the PSFAQ polymer membrane as an electrode can improve its electrochemical performance through pores and exposed anthraquinone-hydroanthraquinone redox couple. Zinc ion battery (ZIB) was assembled with PSFAQ membrane and metallic zinc as the electrode pair. This research proposes a new, safe, and inexpensive material that can be used for water system energy storage.

Key Words:Polymeric membrane, Polysulfone grafted anthraquinone-hydroanthraquinone, Water-based battery
