The Advancing Sodium-Ion Batteries: From Materials to manufacturing, Prototypes and Applications symposium covers the full spectrum of sodium-ion battery (SIB) research, from fundamental science to applied solutions. The event will explore the underlying mechanisms that drive SIB performance, with a focus on advanced materials, electrode designs, and novel manufacturing techniques. A central theme will be understanding ageing and degradation mechanisms, as well as the fundamental processes that influence long-term battery stability and efficiency. Discussions will also address the challenges of scaling up from fundamental research to prototype development, including material optimization, performance validation, and sustainability considerations. The symposium will emphasize applied solutions aimed at enhancing energy density, cycle life, and overall performance, ensuring that scientific innovations translate into real-world applications. This platform will foster cross-disciplinary collaboration, bridging the gap between theoretical research and practical implementation, and advancing sodium-ion battery technology toward commercial viability.
