Moreover, by fabricating the cell with a discharged cathode, it is the capacity of the cathode that determines the capacity of the cell. Nevertheless, the E FA of the carbon anode is only 0.2 eV below the E FA of Lithium, so the cell has a high specific energy QV because of its V ≈ 3.8 V. The cell also has a high volumetric energy density ...
