INERRANT aims to drive genuine advancements for safe-and-sustainable-by-design materials, and eco-friendly processes, to ensure the economical and widespread utilization of safer LIBs tailored for the expanding electromobility applications in our modern society. To realize this, INERRANT is formulating a holistic approach to enhance safety performance, extend cyclability and operational lifespan, and improve fast charging, all while maintaining cost-effectiveness, energy, and power density, and avoiding dependence on Critical Raw Materials. The pivotal S&T challenges encompass: development of functional materials, design sustainable recycling processes and understanding of pertinent interfacial phenomena and degradation mechanisms. The project addresses current challenges for LIBs components related to (i) novel (nano)materials combinations for anodes and cathodes; (ii) smart-functioning separators; (iii) stimuli responsive electrolyte formulations; (iv) novel sustainable recycling processes to improve the purity of recovered materials. Novel electrochemical characterization methods and operando spectroscopies, both at the materials and component level, will be utilized. This includes the establishment of a metrological framework for traceable calibrations and the integration of machine learning methodologies for swift and early LIB cell aging predictions. Adopting fabrication methods that are inherently scalable, built upon existing pilot lines and proven safety testing, will facilitate a swift progression to Gigafactory-relevant scales. INERRANT will present a compelling business case and clear exploitation strategy, rooted in the consortium’s strategic insight, guaranteeing effective technology commercialization. This approach will support the economical and eco-friendly production of LIB cells and systems, tailored for e-mobility applications. INERRANT comprises a consortium of 11 partners from the European Commission and one associated partner from the USA.
