Researchers at Sweden’s Linköping University have developed an organic flow battery. Principal research engineer Mikhail Vagin and his colleagues have succeeded in producing a water-based electrolyte and also electrodes of organic material, which considerably increases the energy density.
The team have used the organic conducting polymer PEDOT for the electrodes.
It is claimed this is the first redox flow battery to include organic conducting polymer electrodes operating in both the posolyte and negolyte configurations, thus the first “all‐organic” RFBs. The polymer works with a water-based electrolyte consisting of a solution of quinone molecules.
