Validation of the accuracy of the 12-point scan approach.
(a) Transmission image at E = 8.36 keV, showing sample area considered of a completely charged cell. (b) State of charge (SOC) map obtained from high resolution scan with 47 energy steps. (c) SOC map of the same sample area obtained using only 12 energy steps. (d) Difference in SOC determined using the two different types of scans, showing an average difference over the entire scan area of below 1%. (e) The obtained spectra averaged over all particles in the scan area from the 47 step (black) and the 12 step measurement (blue circles).
