Article Synopsis
- Organic materials like conducting redox polymers (CRPs) are gaining attention for their environmentally friendly and sustainable use in batteries.
- The CRP discussed is made from poly(3,4-ethylenedioxythiophene) with naphthoquinone groups, allowing for easy coating onto current collectors using techniques like roll-to-roll processing or ink-jet printing.
- When tested, this CRP anode achieved a capacity of 76 mAh/g, a discharge voltage of 0.50 V in a polymer-air battery, and maintained 97% capacity after 100 cycles, demonstrating its potential in high-performance energy storage applications.
Electrodes based on organic matter operating in aqueous electrolytes enable new approaches and technologies for assembling and utilizing batteries that are difficult to achieve with traditional electrode materials. Here, we report how thiophene-based trimeric structures with naphthoquinone or hydroquinone redox-active pendent groups can be processed in solution, deposited, dried and subsequently polymerized in solid state to form conductive (redox) polymer layers without any additives. Such post-deposition polymerization offers efficient use of material, high mass loading (up to 10 mg cm ) and good flexibility in the choice of substrate and coating method.
