Sodium-ion batteries (SIB) have emerged as a promising alternative to lithium-ion batteries (LIB) due to their potential for lower costs, abundant raw materials, and environmental benefits. However, the lack of established recycling processes poses significant challenges to their sustainable use in the future. This thesis investigates the state of the art in SIB technology and explores potential recycling strategies with a focus on efficiency and environmental impact. A comprehensive analysis of current SIB materials, designs, and applications is conducted, followed by a summary of existing recycling concepts from both research and patents. Theoretical recyclability calculations are performed, and three potential recycling processes are proposed and evaluated. The study also highlights the importance of integrating eco-design principles to improve the recyclability of difficult-to-recycle components such as binders and electrolytes. The findings suggest that while SIB recycling is technically feasible, significant advancements are needed to optimize economic viability and environmental sustainability. The research concludes with recommendations for future development, emphasizing the need for enhanced recycling infrastructure and the incorporation of sustainable design practices.
