Overview of the 4SIBAT Project
Solid-state sodium-ion batteries (SSSIBs) are emerging as the most efficient near-term solution for energy storage that avoids the use of critical raw materials. However, there is still a need to develop materials that can be used in the electrodes and electrolyte to meet the performance requirements in terms of energy density and stability. 4SIBAT project pursued the design and production, through efficient and scalable processes, of (i) sustainable carbon materials from green monomers and (ii). optimized solid-state electrolytes based on hybrid conductive gel-polymer and single ion membranes. By combining these innovative and sustainable components it is intended to have, at the end of the project, a prototype of Sustainable-SSSIB (4SIBAT) with an optimized architecture able to competitively meet the demands of a robot in real operating conditions. With the 4SIBAT project we contribute to the EU’s ambition to become a world leader in renewable energy and its secure supply.
Key Objectives of the 4SIBAT Project
4SIBAT will produce innovative and advance materials for the anode and the electrolyte of SSSIBs, based on abundant, sustainable, non-toxic and cost-effective precursors and throughout innovative and highly efficient processes (microwave assisted sol-gel methodology for sustainable carbons and photo-polymerization for solid electrolytes). The integration of these advanced materials into the solid-state sodium-ion battery and their performance monitoring by in-situ/operando characterization techniques will also allow to achieve a systematic understanding, at a fundamental level, of the phenomena governing sodium ions mobility in SPEs and the electrode/electrolyte interaction mechanisms in complex systems, paving the way for significant advancement of sustainable energy storage technologies.
Therefore, taking those issues in mind, the MAIN OBJECTIVE of 4SIBAT would be to produce innovative, sustainable and advanced materials for optimizing the performance of flexible solid-state sodium-ion batteries to achieve their implementation as an energy storage system.
Implementation strategy: Work Plan overview
4SIBAT’s work is structured in five work packages: WP1-WP3 are scientific & technical and focus on synthesis and analysis of anode material development, polymer electrolyte development and advanced characterizations, study of electrode/electrolyte interaction mechanism architecture at lab-scale for flexible solid-state sodium-ion batteries. WP4 will be dedicated to integrate the key findings from WPs 1-3 to create prototype devices and integrate them into an end-use application, enabling the mapping of the performance of solid-state sodium-ion cells. WP5 moves the S&T from WPs1-4 closer to real application by engineering prototype full cells and assess their performance in different environmental operating conditions.
