Sustainable and Safe anode-free Na battery - SuSaNa

Project summary

In the near future the market is going to need large amounts of batteries that require to be sustainable and safe. SuSaNa project aims at developing a sustainable, safe, and high energy density Na-based battery. The focus is put on: (i) formulate novel non-flammable electrolytes with high efficiency of Na plating-stripping, to supress dendrite growth becoming safe, (ii) development of anode-free cells that provide high power and high specific energy, and (iii) using a highly performing patented cathode, Prussian white. Moreover, key processes, products and materials are to comply with Green Chemistry and Green Engineering principles, and Ecodesign concepts including recyclability aspects that will be proposed at early TRLs. To achieve the challenging goals an outstanding consortium from 4 countries has been gathered, with research institutions and universities (Uppsala Univ., DTU, FZ Jülich), start-ups (Altris & PhaseTree) and a recycling company (ACCUREC) led and coordinated by CSIC.
