Sodium-ion batteries (SIBs) have been considered a promising alternative to lithium-ion batteries (LIBs) due to the utilisation of more abundant raw materials and potential for low-cost energy storage. Despite these advantages, SIB technology is currently in its early stages, with many cathode chemistries being investigated and most prototypes still using carbon-based anodes. Recent research has, nonetheless, expanded its focus on anode development to place special emphasis on acquiring a comprehensive understanding of the effects of multiple material choices on the environment. This thesis develops and investigates a life cycle inventory (LCI) for sodium-ion battery anode active materials. The database was used to conduct a preliminary life cycle assessment (LCA) for a lab-scale scenario of certain active materials under different regional power mixes of electricity, e.g., India, Europe (various energy mixes and renewable scenarios).
