A Long Cycle‐Life and Recyclable Anthraquinone Oligomer Connected via Amide Bonds for Use in Rechargeable Organic Batteries

open access: yesBatteries &Supercaps, EarlyView.
This study presents the synthesis of an anthraquinone oligomer linked by amide bonds that demonstrate a long cycle battery performance. Oligomers connected by amide bonds undergo hydrolysis, rendering them easily biodegradable. The concept provides a guideline for a future material design of sustainable batteries. With the increasing demand for energy,

Structure–Performance Relationships in Anthraquinone‐Disulfonate Coordination Polymers for Li‐Ion and Na‐Ion Battery Cathodes

open access: yesBatteries &Supercaps, EarlyView.
Anthraquinone‐disulfonate coordination polymers (AQDS‐Na, AQDS‐Mg, AQDS‐Cu) are synthesized and evaluated as cathodes for Li‐ion and Na‐ion storage. Structural dimensionality and coordinated water critically impact the practical capacity and cycling stability, highlighting design principles for organic‐based energy storage materials.

Enhancing the Energy Density of Zn‐Ion Capacitors Using Redox‐Active Choline Anthraquinone Electrolyte

open access: yesBatteries &Supercaps, EarlyView.
Biocompatible redox electrolytes: The presence of choline chloride in aqueous ZnCl2 electrolyte improves the stability and performance of Zn‐ion capacitor is shown. An enhancement in energy density is achieved by the addition of choline anthraquinone sulphonate redox molecule in the electrolyte. Owing to ease of recyclability, high theoretical capacity
