Operando X-ray absorption spectroscopy applied to battery materials at ICGM
The challenging case of BiSb's sodiation
X-ray absorption spectroscopy (XAS) is a synchrotron-based, element-specific, short-range structural method largely used in the study of materials, already widely employed for the study of the electrochemical processes in battery systems. The high penetration of the X-rays mak ...
Elucidating the origin of superior electrochemical cycling performance
New insights on sodiation-desodiation mechanism of SnSb from: Operando spectroscopy
As it has been recently shown in the literature, SnSb exhibits better performance in Na-ion than in Li-ion batteries in spite of its even larger volume expansion. Where is this special behaviour coming from? In this work, the reversible sodiation-desodiation reaction of SnSb w ...
The electrochemical sodiation of sb investigated by Operando X-ray absorption and 121 sb mössbauer spectroscopy
What does one really learn?
In this study, we want to highlight the assets and restrictions of X-ray absorption spectroscopy (XAS) and Mössbauer spectroscopy for investigating the mechanism of the electrochemical reaction of antimony electrode mat ...
