B2B: Transferring bio-based materials into batteries

The need for energy storage capacity is drastically increasing because of the decarbonization of energy supply, i.e. replacement of the fossil energy supply by green intermittent renewable energy. In the B2B project, we propose organic radical polymer battery as an alternative technology to lithium batteries with the general aim of minimizing usage of any critical raw material in the designed devices. Overall, the strategy is to synthesize polyradicals as positive electrodes and optimize biocarbons for negative electrodes, as well as to combine these to one energy storage solution with nanocellulose-based gel electrolytes.

Main results

  • We have accomplished to narrow down the optimal processing parameters for biocarbons

  • Implementation of the most promising materials into batteries is ongoing

  • We have completed the optimization of synthesis for poly(radical) material for organic radical ion batteries. Electrode preparation and electrochemical studies are ongoing.
