To conduct a similar evaluation on negative electrode active materials (NEAMs), we realised that the battery section of MP did not contain, to date, entries for commercially available ones. We then proceeded to manually add two entries, marked with an asterisk, titled graphite (Li0-1C6*) and LTO (Li4-7Ti5O12*). Their specifics are reported in Table in SI. When compared to the other materials, graphite performed exceptionally well in terms of theoretical specific capacity, scoring in the top 99.4 percentile. Its exceptionality as a NEAM is then further confirmed by the outstandingly low average operational voltage: it indeed scores as the lowest of all in the dataset. LTO, on the other hand, seems to make for a reasonably good NEAM, scoring in the top 77.9 percentile by theoretical specific capacity and in the 4th percentile by operational voltage. It is important to notice, though, that this rather small shift from 0th percentile to 4th is accompanied by an increase in average operational voltage of more than 1.5 V. This is due to the low number of AMs operating at voltages below 1.5 V, as can be observed in Figure (a). The AMs specific capacity distribution is visualized in Figure (below). Numeric values are also reported in Table . Before running the VOLTA pipeline, the AMs were filtered, in order to exclude the phases too unstable and the AM operating outside the practical stability window of a conventional liquid electrolyte, i.e. 0 to 4.5 V The number of AM left was 2028. Moreover, the electrode construction parameters are the same as in Section 4.1: the electrodes' thicknesses are calculated from the mass loadings and porosities output by the Artistic calculator (reported in Table in SI). After the cell building step, only the possible cells were considered (Possibility boolean evaluating to True, see Section 3). The cells with voltage spread above 0.6 V were also excluded, not to exceed the stability window of the electrolyte too much. Table reports all the filtering criteria for AMs and for the constructed cells.
