  1. Experimentally, the electrode mass of lithiated copper-deposited carbon fabric (Li/CuCF) anode with high areal capacities of 6 mA h cm−2 was measured to be 8.6 mg cm−2. To increase the areal capacity of Li-S full batteries, the NSHG/S8/NiCF cathode (NSHG is nitrogen and sulfur heavily doped graphene and NiCF is nickel-deposited carbon fabric) with various electrode mass of 10.5, 13.1, and 14.5 mg cm−2 was prepared to pair with the Li/CuCF anode. The measured thickness of metallic fabrics/electrodes is ~150 µm under standard stress (400 N cm−2, a pressure used for the compression of standard coin cells). The thickness of the separator is typically ~25 µm. The gravimetric and volumetric densities are calculated based on the total weight and volume of the entire battery including current collector, electrode, and separator
