Abstract [en]

To solve for future energy needs, the capacity of storing energy will be crucial when energy production from renewables increases. In principle all of today’s batteries are made of metals, which are energy demanding both to extract and recycle, as well as being non-renewable. An example is lithium ion batteries (LIBs), which today are unprofitable to recycle (due to the high temperatures needed), hence remaining deposits will not last for long if we want electric vehicles based on LIBs to replace conventional vehicles. Additionally, an electric car must be charged over 120 times before it even reaches a negative CO2 impact, compared to conventional cars. A solution to this problem is to make batteries with the same or higher charge capacity as conventional batteries, but from renewable sources.

Quinones have high specific capacity and function as charge carriers in natures’ photosynthesis and respiration cycle. When combined with a polymeric backbone, the resulting material has potential of becoming a cheaper, lighter and greener alternative to LIBs.

Conducting redox polymers (CRPs) have been proposed as a renewable alternative for electrode materials. CRPs consist of two parts: a conducting polymeric (CP) backbone, such as polypyrrole (PPy) or Poly(3,4-ethylenedioxythiophene) (PEDOT); and a redox active side group, such as quinones, attached to the backbone. For the system to function as a battery, the attached redox group must be active in the same potential window as the specific polymer is conducting.

This project aims at finding, synthesizing and characterizing high charge capacity materials and targeting renewable organic batteries for a future of sustainable energy storage.
