Alluaudite Class of High-Voltage Cathodes for Sodium-Ion Battery Applications: A Synthesis, Structure, Property Correlation Study

Abstract

The work presented in this thesis demonstrates alluaudites as a niche class of compounds forming the rich treasure house of sodium insertion hosts. The potential of this open frame-worked alluaudites is immense and further research will open up newer domains of applications. The current thesis work has also elucidated in-depth crystal/ magnetic structure analysis and Rietveld refinement of these novel compounds by combining X-ray, neutron and synchrotron diffraction techniques. It has also explored the synthesis of various metastable phases and polymorphism at different synthetic conditions to gauge their structural and electrochemical properties
