Synthesis and characterization of Na-Fe-Mn-Ni-oxide cathode materials for sodium-ion batteries

Sodium-ion batteries (SIBs) present a promising alternative to lithium-ion batteries, attracting significant interest due to their low cost and the abundance of sodium resources. Among the key cathode materials for SIBs are sodium transition metal oxides containing Ni, Mn, and Fe. Depending on their metal composition and defect concentration, these oxides exhibit different crystallographic phases, leading to variations in their material and electrochemical properties. This master thesis is part of a broader project aimed at investigating the material and electrochemical properties of a wide range of sodium-based cathode materials. Building on our recent research on lithium-ion battery cathode materials, the primary objective of this thesis is to synthesize and characterize selected cathode materials within the Na-Fe-Mn-Ni oxide system and identify property trends. Through this project, the student will gain hands-on experience in cathode material synthesis and characterization techniques, including X-ray diffraction (XRD) and scanning electron microscopy (SEM), as well as in cell assembly and battery testing. Students with a background in materials science or chemistry are encouraged to apply. Show detailsaddremove
