Battery energy density measures the amount of energy stored per unit of mass or volume (Wh/kg or Wh/L). Higher energy density enables longer runtimes, lighter weight, and more compact designs—fueling advancements in electric vehicles, portable electronics, and grid storage.
The ratio of cell density to pack density is 0.6235 and this is very close to the total cell to pack mass relationship of 1.6034 The usable energy (kWh) of the pack is fundamentally determined by: Energy (kWh) = S x P x Ah x V nom x SoC usable / 1000
In order to estimate the mass and volume of a battery cell, we assumed a specific geometry based on current cell formats available at the BLB. The cell manufactured is composed of stacked electrodes as described in Figure S1. The material inventory of the cell produced for each of the battery systems is reported in Tables S4.1-S4.3 and S5.1-S5.4.
