Analysing operando Mössbauer spectra of battery materials: a chemometric approach to the study of NaFeO2 as positive electrode material for Na-ion batteries

noteworthy that a rapid degradation of the cell performance begins in C2, indicated by a long flat plateau in charge with a capacity exceeding the one obtained from discharge (

While the relative energy-dependent anisotropy defined above is useful in studying individual events, for statistical purposes it has three drawbacks: (1) for quantifying the

Figure G.C.1 shows indeed that these new sulfate compounds, in particular Li2Fe(SO4)2, rank at the top of the scale of potentials for the iron-based polyanionic materials

Studied areas show an important erosion of the shoreline (with a maximum of -26 m ± 5 m) and a major extension of the sebkha Marsett Essendouk (+52% in 47 years). These two

According to a Kolmogorov-Smirnov test, this histogram can be con- sidered as a normal distribution (h=0, p=0.03), and we can thus evaluate, for each para- meter, the dispersion of
