LCO and LNO display a clear monotonic growth, signifying that for increasing cell energy an increasing share of cells contains either of these as positive electrode active materials. It is also worth mentioning that their volumetric theoretical capacities score in the top 99th percentile. The observed trend is reasonable, being that such electrodes score so well in terms of theoretical capacities and display a rather high average operational voltage. LFP, on the other hand, displays a monotonic decrease, that plummets when considering the top 1 percent of cells. Being that LFP's average operational voltage is close to the dataset mean (45.9th percentile), the trend can be justified by the lower theoretical specific capacity (78th percentile), and theoretical volumetric capacity (74th percentile) typically associated with species like polyanionic compounds.
