The data includes:

-XRD and Raman patterns of the films (Fig. 2)

-Cyclic voltammograms and charge-dischage profiles of the different films (Fig. 4)

-Capacity vs. C-rate for the different flms (Fig. 5)

-Capacity vs. cycle number at different electrochemical window (Fig. 6)

- Operando Spectroscopic Ellipsometry - Including operando charge-discharge profile vs time in the extended voltage window, the imaginary part of the permittivity as a function of energy, and extracted ellipsometry data, the amplitude of the second oscilator and the imaginary part of the permittivity at 1.5eV as a function of time (Fig. 7)
