Solving the challenges of Na-ion battery electrodes

Sodium layered oxides, NaxMO2 (M = Ti – Cu), show great promises as positive electrode material candidates for Na-ion batteries. However, detailed structural analysis of these materials presents many difficulties owing to their reactivity in ambient conditions, numerous structural transitions as a function of the sodium content and extended stacking fault occasionally resulting in partial amorphization of the sample.

This webinar will cover the study of P2-NaxFe1/2Mn1/2O2 positive electrode material focusing on the powder X-ray diffraction (PXRD) data collection strategies used to address the challenges inherent to sodium layered oxide in general. The wealth of information accessible owing to the outstanding versatility of the multipurpose Empyrean platform will be exemplified through the following techniques:
• Debye-Scherrer geometry to characterized unstable phases.
• Thermodiffraction under controlled atmosphere to understand the reactivity of the material.
• Operando monitoring of the crystal structure of the electrode.
• Pair Distribution Function (PDF) analysis to reveal the structure of semi-crystalline compounds.
