The primary objective of this research proposal is to comprehensively investigate the Mo-doped LiCoO2 cathode material using X-ray Absorption Fine Structure (XAFS). Our study aims to achieve the following: (i) Characterize LiCoO2 Properties: Provide an in-depth understanding of the pristine LiCoO2 cathode material, emphasizing its specific properties such as crystal structure, electronic configuration, and redox behavior. Highlight the electrochemically unfavorable aspects that limit its performance in rechargeable lithium-ion batteries. (ii) Mo Substitution Strategy: Explore the potential of Mo substitution as a remedial approach. Investigate how incorporating Mo into the LiCoO2 lattice can mitigate the material’s shortcomings, enhance its stability, and improve its electrochemical properties. (iii) Correlation of Structural Changes and Performance: Utilize XAFS measurements to correlate structural modifications induced by Mo doping with battery performance. Specifically, assess how changes in Co oxidation states, local coordination environments, and lattice distortions impact Li-ion diffusion kinetics, capacity retention, and cycling stability. (iv) Guidelines for Optimized Cathode Design: Based on our findings, propose guidelines for designing high-performance Mo-doped LiCoO2 cathodes. Consider co-doping strategies, optimal Mo content, and the interplay between structural features and electrochemical behavior.
By achieving these objectives, we aim to contribute valuable insights to the field of advanced energy materials, facilitating the development of next-generation lithium-ion batteries.
