Radical Oligomer-Grafted Cellulose as Cathodes for Sustainable Aqueous Zinc-Ion Batteries.

ABSTRACT: Organic electroactive materials are widely used in aqueous zinc-ion batteries (AZIBs) due to their versatility in chemical modification for enhanced electrochemical performance. Redox-active polymers (RAPs) are particularly appealing because of their low solubility, which reduces capacity fading, and their amorphous structures enable easier processing and faster ion diffusion compared to crystalline electrode materials. Current RAPs employed in AZIBs are primarily conjugated aromatic polymers or aliphatic polymers with CC bonds, which can potentially contribute to microplastic pollution at the end of the battery's life. In this work, natural cellulose is selected as the parent polymer and, through chemical grafting, introduced radical oligomers to afford cellulose-g-oligo(TEMPO) as electr
