Comparison of theoretical (theor.) and/or experimental (exp.) values of specific surface area (SSA), electrical conductivity (σ) and specific capacitance (C_sp) of different carbonaceous materials such as activated carbon, graphene and single-wall carbon nanotubes (SWCNT).

	Activated Carbon	Graphene	SWCNT
SSA, m²/g	~3000 (theor. [3])	∼2600 (theor. [5])	1315 (theor. [5])
σ, S/m	4.6 × 10⁻⁶ (exp. [4])	~10⁸ (theor. [6])	~10⁶ (exp. [8])
σ, S/m	4.6 × 10⁻⁶ (exp. [4])	~10³ (exp. [6])	~10⁶ (exp. [8])
C_sp, F/g	200 (exp. [3])	~550 (theor. [7])	180 (exp. [9])
