Quantifying static capacity losses in solid-state battery composites via coulometric titration comparison

An electrochemical method is discussed to quantify in situ the static CAM utilization, i.e., the fraction of electrochemically active mass in solid-state battery composite cathodes. For that, coulometric titration curves of the same active material in cells with solid and liquid electrolytes are compared. The results are contrasted with an ex situ method based on X-ray diffraction.
