NASTOR

The NASTOR project is focused on the development of new flow batteries (Redox-Flow) for stationary energy storage. These batteries aim to respond to the challenges of renewable energy storage, particularly the intermittence of sources such as wind turbines and solar panels. By using aqueous solutions of redox mediators and sodium insertion materials, the project aims to increase energy density without using toxic metals. The NASTOR project is aiming to produce a pilot battery integrating all the expertise developed by the consortium (sodium insertion materials, porous boosters, aqueous mediators, current collectors and membranes). IMT Nord Europe’s Materials & Processes CERI (Centre d’Enseignement, de Recherche et d’Innovation, Center for Education, Research and Innovation) is involved with development of extruded porous composites as immobilized in-tank boosters. These are hybrid monolithic structures with high internal diffusivity well suited to these batteries, and an extrusion-dissolution process is being studied to consider medium-term industrialization. The work is focused on elaborating advanced formulations based on LFP (Lithium Iron Phosphate) or NTP (Sodium Titanium Phosphate) combined with PVDF and PEO-type porogens. Fundamental studies are ongoing at a morphological and electrochemical level.
