RESEARCH INTEREST

With the increasing need for sustainable and economical energy storage solutions, sodium-ion batteries offer promise due to the abundance and lower cost of sodium resources compared to lithium. My research focuses on exploring layered oxides for application as cathodes in sodium-ion battery (SIB). Layered oxide cathodes play a crucial role in determining SIB performance, impacting factors such as energy density, cycling stability, and overall efficiency.

My goal is to design, synthesize, and characterize novel layered oxides. Through advanced materials engineering techniques, I aim to improve the electrochemical performance of these cathodes, addressing challenges such as structural stability, capacity fading, and rate capability. Additionally, I aim to understand the fundamental electrochemical mechanisms and kinetics involved in the sodiation and desodiation processes of layered oxide cathodes.

The outcomes of this research have the potential to significantly advance the development of high-performance and cost-efficient sodium-ion batteries, thereby contributing to progress in energy storage technology and facilitating the transition to more sustainable and accessible energy solutions.
