The five unintercalated materials we have considered are Mn4NiO8,FeO2,Fe(CoO3)2,V5O12 and CoPO4. The structures of the system have been taken from Materials Project database. The fully intercalated systems with maximum capacity are represented in Figure . data and that of DFT are presented in Table . Thus we can see that our ML results are very close to the independent DFT results and can be used as alternative for time consuming DFT calculations in general.
