For finding out the correlation among the features we have also generated the heat map. The heat map has shown in Figure was generated by the correlation function from the seaborn library. The features are listed in the supported information. From the correlation values of different features in the heat map (Figure ), it has been observed almost all the features are independent of each other, some descriptors are positively correlated, and some are negatively. This result proves the choice of these descriptors will be able to represent each electrode materials uniquely. Though there are very few elemental descriptors which are dependent of each other, we can't drop those descriptors since those descriptors represents the ions which are getting intercalated. The list of elemental features used in the heat-map (fi) is attached with the Table (Supporting Information). Understanding the nature of different features is highly important and, in this regard, distribution plot help us to find out the density of every feature. Here we have shown distribution plot of some selected descriptors as these descriptors are very impactful on determining the capacity, rest of the plots are attached with the supporting information (SI). Some of the descriptors has been taken to produce joint plot across the capacity of the electrode for finding out some insight and dependency of the dependent variable on the independent variable. The joint plot of the selected descriptors are taken by intuition as we were keen to know whether these descriptors plays important role from chemical point of view or not.
