Figure : top 17 low-voltage virtual cells by area capacity. As in Figure , area capacity was chosen to allow extrapolation of the result to arbitrary cell geometries (above). Capacity per mass of active material (sum of both PEAM and NEAM) is also reported Figure : distribution of MP electrode entries in a specific capacity vs voltage plane; the distribution is displayed with contour lines obtained with kernel density estimation, showing the density of datapoints in the specific capacity vs voltage space. Given the AM pairing rules reported in table 5, the three AM highlighted can only be paired with AMs that operate at 0.6 and 1.2 V more (or less). For the sake of graphical simplicity, we assume Li 0-1 TiNCl and Li 0-1 VS 2 to only behave as NEAMs and Li 0-1 CuO 2 as PEAM, i.e. to seek counter-AMs only in the voltage regions above and below themselves, respectively.
