At first glance, we observe how relevant graphite is as a NEAM in this battery revealing problem. Its low operational voltage and high theoretical capacity, which we discussed above, make it a good NEAM to match with a number of possible PEAMs. On the PEAM side, we observe mainly transition metal oxides, including the commercial, wellknown Li 0-1 CoO 2 . Two different Li 0-1 MnO 2 entries appear, too. These are referred to two separate MP elecrode objects(mp-18767_Li and mp-33009_Li), thus highlighting that VOLTA does not explicitly take into account crystallographic information. Such an approach is not to be considered as "composition-only", though, as VOLTA distinguishes polymorph AMs; it becomes necessary, though, to determine from the MP database the structural differences. In the present case, mp-33009_Li is obtained from virtual lithiation of rutile-structured MnO 2 (mp-510408, observed), while mp-18767_Li is obtained from the virtual delithiation of orthorombic Li 0-1 MnO 2 (mp-18767, observed). The highest performing cell is obtained by combining graphite and Li 0-2 CrF 4 . This reasonably follows from the intuition that high capacity is also linked to multiple reduction steps on the active transition metal and that voltage can be increased by inductive effect shifting from oxides to halides. The ability of VOLTA to identify likely battery candidates is thus demonstrated. The MP entry IDs of the identified materials are reported in Table in SI.
