This book investigates the electrochemical performance of vanadate and molybdate compounds as electrode materials for lithium-ion batteries. The study focuses on three structurally related compounds, MVMoO7 (where M = Fe3+, Cr3+, Al3+), examining their suitability for energy storage applications. It details how variations in the trivalent counter-cation (Fe3+, Cr3+, Al3+) influence the redox potentials of the V5+/V4+ and Mo6+/Mo5+ couples, providing insights into the energetic landscape of the electrochemical process. The research quantifies the lithium insertion and reversible extraction capabilities of each compound, highlighting differences in their electrochemical behavior and stability.

This work presents a focused study on the electrochemical properties of specific vanadate and molybdate compounds for lithium-ion battery electrodes. The research provides quantitative data on lithium insertion, reversible capacity, and cycling stability for FeVMoO7, CrVMoO7, and AlVMoO7. The findings suggest that AlVMoO7 exhibits superior reversibility and stable capacity retention compared to its iron and chromium counterparts. The study's conclusions emphasize the significant role of the counter-cation in tuning the electrochemical performance of these materials.
