[LIB Electrode Slurry Analysis] What is "Goodness of fit"?
QWhat is “Goodness of fit” item in the result file?
“Goodness of fit” value expresses the extent to which the calculated impedance approaches the measured impedance. When the value is closer to 1, the smaller the relative difference between the measured impedance and the calculated impedance.
“Goodness of fit” is defined as follows :
Here Rs,meas,i and Xmeas,i indicate the measured impedance; Rs,calc,i, Xcalc,i, the calculated impedance; and T, the average measured impedance.
“Goodness of fit” provides a numerical indication of the calculation status. It does not indicate slurry quality.
