Project description
Mitigating thermal runaway propagation in sodium-ion batteries
Unlike lithium-ion batteries, sodium-ion batteries are not reliant on rare earth and toxic heavy metals, making them more eco-friendly, less costly and safer. Despite these advantages, sodium-ion batteries face thermal runaway propagation risks, the mechanisms of which are largely unstudied. Supported by the Marie Skłodowska-Curie Actions programme, the RuNaWay project addresses this research gap, seeking to shift safety strategies from reactive to proactive by building a robust, predictive safety framework for next-generation sodium-ion batteries. The approach combines multiscale modelling with operando optical diagnostics, which links real-time physical observations with theoretical, mechanistic simulations. This allows researchers to detect structural degradation early on and identify the root microstructural causes of material failure.
Objective
In the context of global climate challenges and the transition towards renewable energy sources, sodium-ion (Na-ion) batteries are emerging as a promising alternative to lithium-ion (Li-ion) batteries, offering reduced dependency on critical raw materials and enhanced sustainability. However, despite their theoretical safety advantages, the thermal runaway mechanisms and associated safety risks of Na-ion batteries remain largely unexplored.
The first objective of this project is to address this critical knowledge gap by developing a comprehensive, predictive safety framework for Na-ion batteries. The second objective of this study is to transition from reactive to proactive safety strategies by detecting early-stage failure indicators in real time, with a particular focus on the gaseous precursors emitted during thermal abuse. The integration of operando optical diagnostics with multi-scale modelling is a novel approach that has the potential to deliver two key benefits. Firstly, it will facilitate the delivery of early detection capabilities. Secondly, it will enable material-level insights to be gained into failure mechanisms.
To conclude, this project will establish the foundations for the development of energy storage technologies that are safer, more scalable, and less reliant on lithium. These technologies will contribute to Europe's aspirations towards achieving climate neutrality and will also serve to strengthen its strategic autonomy in the field of battery innovation.
