Electropolymerized Bipolar Poly(2,3‐diaminophenazine) Cathode for High‐Performance Aqueous Al‐Ion Batteries with An Extended Temperature Range of −20 to 45 °C

Wei Wang,

et al.

Abstract: Achieving reversible insertion/extraction in most cathodes for aqueous aluminum ion batteries (AAIBs) is a significant challenge due to the high charge density of Al3+ and strong electrostatic interactions. Organic materials facilitate the hosting of multivalent carriers and rapid ions diffusion through the rearrangement of chemical bonds. Here, a bipolar conjugated poly(2,3‐diaminophenazine) (PDAP) on carbon substrates prepared via a straightforward electropolymerization method was introduced as cathode for A… Show more

“…17,18 Electropolymerization is a facile method in generating large πelectron-conjugated polymers that are conductive, for example, poly(1,5-NAPD), 19 poly(aniline-co-azure B) (PANAB), 20 and poly(2,3-diaminophenazine) (PDAP). 21 To construct a cathode material for aqueous ZIBs, abundant redox active groups including carbonyl and imino groups are essential to improving the specific capacity. A dihydropyrazine derivative, 6,9-dihydropyrazino[2,3-g]quinoxaline-2,3,7,8(1H,4H)-tetrone (DHPQ-Tetrone), has a nitrogen-containing heteroacene structure, which is modified by four carbonyl groups.…”
