The accuracy of VOLTA can be pushed even further by using experimental cycling data, more precisely extreme voltages and associated capacity. This would result in more realistic cell voltages and capacities, and also circumvent the need for theoretical viability metrics for the materials experimental data is available for, as they must have been synthesised to gather the cycling data in the first place. The use of observed materials only, with their respective measured voltage and capacity data would thus allow for more pragmatic battery revealing tasks. This would come to the cost of reducing the screening to less AMs, and of needing extra care in collecting the experimental data in conditions as uniform as possible across different AMs. Moreover, improving the stability metric SM to a more thorough synthesizability assessment for each virtual AM would be a valuable addition to VOLTA, too. This would allow for a more accurate assessment of the practical viability of virtual cells that might be identified as particularly desirable.
