The demand for secondary batteries is constantly increasing with the rising trend of connected devices and increasing effort to dramatically reduce fossil fuel consumption in society. Apart from conventional metal based batteries, batteries consisting of[UU1] naturally occurring organic materials can be envisioned, thus becoming fully sustainable and avoiding the negative environmental impact associated with the production and recycling of conventional metal based batteries. One class of fully organic batteries utilizes conducting redox polymers (CRPs) as electrode materials. 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. In the current work a concept and initial results for a metal-free, fully organic battery based on CRP electrode materials are presented. Challenges and possibilities with building this new type of battery are discussed.
