The transition to renewable energy sources requires efficient energy storage technologies produced from widely available and sustainable materials. In the STORAGE project, we aim to develop a stable and sustainable organic radical battery which does not use critical raw materials (CRMs) typical in other battery types. The battery will utilize polymer-supported organic radical as the cathode material, biomaterial-based hard carbon as the anode material and sodium-conducting cellulose-based gel electrolyte. To realize the CRM-free battery with exceptional electrochemical performance, we will refine the synthesis and properties of these battery components, upscale the syntheses to 10-100 gram scale, as well as investigate and develop sodium compensation technologies critical for the creation of high-performing sodium-ion batteries.
Main results
We have upscaled the synthesis of the polymer-supported radical to gram scale, which will allow us to focus on developing an electrode manufacturing process.
Lab-scale pre-processing and electrode manufacturing processes have been developed for biocarbon materials.
Cell setups to allow effective electrochemical pre-sodiation are under development.
