Abstract

The growing demand for renewable energy drives the development of cost effective and sustainable energy storage technologies. Sodium-ion batteries (SIBs) have emerged as a promising alternative to lithium-ion systems due to the natural abundance, low cost, and wide availability of sodium. This research focuses on the synthesis and characterization of layered transition metal oxide cathodes for SIB applications. Cathode materials were synthesized using high temperature solid state methods. Structural characterization using X-ray diffraction (XRD) enabled evaluation of phase formation and crystallographic properties. Electrochemical performance was assessed through the fabrication and testing of coin cells, allowing for analysis of capacity, cycling stability, and rate capability. The relationship between composition, structure, and electrochemical behavior is investigated to better understand the factors impacting sodium intercalation and long term performance. These results contribute to the ongoing effort to design high performance, sustainable cathode materials. Additionally, this work provides insight into the relationships between structure and properties that are critical for advancing sodium-ion battery technology.
