The development of sustainable, high-performance cathode materials is crucial for advancing zinc-ion battery technology. In this study, we introduce a strategy synthesizing azo polymer via in situ electrochemical polymerization nitro-substituted compounds. This process involves the reduction nitro groups to form N═N linkages, which function as redox-active sites, enabling efficient energy storage. We focus on 2,7-dinitropyrenetetraone (DNPTO), conjugated carbonyl compound, produce material with dual functional groups. Experimental results, supported by theoretical calculations, demonstrate that initial discharge cycle irreversibly reduces groups, leading enhanced performance. DNPTO exhibits 2-fold higher capacity than PTO and significantly improved retention compared mononitropyrenetetraone (MNPTO), attributed its polymerization. study highlights potential electrochemically synthesized polymers promising aqueous ZIBs.
