Abstract

In this study, graphene-wrapped poly(1,4,5,8-naphthalenetetracarboxylic sulfonyl)imine (PNSI/EG) served as a redox-active anode material for aqueous zinc-ion batteries (AZIBs). It yielded a reversible and stable capacity of 173.3 mAh g−1 at 0.1 A g−1, enabling a Zn-metal–free AZIB to deliver a high energy density of 50.1 Wh kg−1.
