Battery people keep comparing apples, and oranges. Battery pack energy density, battery, single cell, cathode, and their rated, nominal, and absolute capacity are all different things. A single cell will always have > absolute capacity than the capacity at which the safety limiter will cut-off charging, and that will be > than the capacity to which BMS will charge/discharge the cell in daily use. It may well be possible for a cathode material to excel in a small pouch cell, but have terrible thermals preventing its use in larger cells.
