Abstract Scope |
Aluminium is a promising material as an alternative green energy storage solution thanks to its very high volumetric energy density (23.5 kWh/L) and full recyclability. CO2-free aluminium could be produced from renewable energy sources through an electrolytic process by using vertical inert anodes and wetted drained cathodes as a sustainable substitute to the Hall-Héroult process with horizontal carbon anodes and cathodes. Ni-Fe-Cu alloys have emerged as a strong candidate for inert anodes. Our work aims to undertake a systematic investigation of the anode properties (corrosion resistance, cell stability, purity of resultant aluminium) as a function of the alloy composition to determine an optimal composition range for the inert anode and vertical electrolysis cell performance. Electrolysis tests and oxidation studies at the laboratory scale will be performed to then inform the up-scaling process. |
