LFP is 20 to 40 percent cheaper than NMC cells, but NMC is up to 80 percent more energy-dense than LFP. A battery cell with an NMC cathode has a nominal voltage of 3.7V, and the energy density range is between 150 to 300 Wh/kg. On the other hand, LFP is at 3.0-3.2V nominal voltage, and its energy density range is roughly 90-160
As a result of the greater quantity of active materials, 20700 cells have an increased capacity of over 0.9Ah, and 21700 cells have an increased capacity of about 1.35Ah compared with 18650 cells. Increasing cell size results in a better ratio of energy-storing versus non-energy storage materials.
