From the Figure , it is observed that molecular weight and polarizability follows almost same trend whereas specific heat values are diverse at higher magnitude. There is an indirect correlation between molecular weight and polarizability as electron density increases with the increase in atomic mass. Therefore, it is very likely to observe the similar tendency between these two parameters. We have not observed any trend in change of capacity with respect to average Pauling electronegativity. The high range of electronegativity for most of the electrode materials can be the cause for this as it overestimates the capacity for the overall data set with respect to this feature.
