The widespread use of fossil fuels today has a devastating effect on the environment. This situation necessitates the adoption of environmentally friendly alternative energy sources. Zinc-ion batteries represent a new, developing class of energy storage systems with significant potential in this regard. However, a major challenge in advancing this technology is developing efficient and reversible cathode materials that can accommodate Zn2+ ions. Quinone-based conjugated polymeric materials are excellent cathode choices for zinc-ion batteries due to their redox-active structures, easily modifiable structures, and strong chemical and thermal stability. This study synthesized two quinone-based redox-active polymers (QRPs) as cathode materials for zinc-ion batteries (ZIBs). The inherent properties of QRPs ensure effective Zn2+ diffusion into their redox centers, guaranteeing long-term cycling stability. QRP-1 and QRP-2 cathodes delivered discharge capacities of 180 mA h g-1 and 134 mA h g-1, respectively, at 0.1 mA g-1. Remarkably, QRPs maintained long-term cycling stability at 2.0 A g-1 over 10000 cycles, with final specific capacities of 42 mA h g-1 for QRP-1 and 104 mA h g-1 for QRP-2. We believe that this work demonstrates the potential of quinone-based conjugated polymeric materials as effective cathode materials for zinc-ion batteries and will attract the attention of energy storage researchers.
