Flexible All Organic Batteries Based on Conducting Redox Polymers

• Batteries consisting of naturally occurring organic materials can be envisioned as sustainable alternatives to conventional metal-based batteries, thusavoiding the negative environmental impact associated with the production and recycling of the latter. In this way the negative environmental impact of theconstantly increasing demand for secondary batteries can be decreased. Apart from being fully organic, such batteries also open up for flexible batterydesigns as they can be produced in a roll-to-roll process and they are anticipated to be viable in a broad range of applications as energy supplies ininnovative flexible electronics designs. In the current work, fully organic batteries are realized utilizing conducting redox polymers (CRPs) as electrodematerials. CRPs combine the high charge storage capacity of a redox active pendant group (PG) with the conduction properties of a conducting polymer(CP) backbone, both to reduce the need for addition of conductive carbon black and increasing the stability of the PG redox conversion in a battery setup.The first results from a fully organic, aqueous battery based on CRP electrode material are presented. Challenges and possibilities of this type of battery in flexible battery designs are discussed.
