Trassatti’s method.-- Supplementary tables.-- Supplementary figures.-- Trassatti’s method: In Trassatti’s method, the charge (q) in the voltammetry test is assumed to depend on the scan rate (υ) as follows: q=q_∞+a_1 υ^(-1/2) (S1) 1/q=1/q_T +a_2 υ^(1/2) (S2) where a_1 and a_2 are constants, q_∞ is the charge not limited by ion diffusion (υ→∞), and q_T is the total cell charge (υ→0). If the measurements are carried out under the same conditions, they can be applied in terms of capacitance as follows: C_((υ))=a_1 υ^(-1/2)+ C_EDL (S3) 1/C_((υ)) =a_2 υ^(1/2)+ 1/C_T (S4) where C_EDL is the capacitance arising from the electric double-layer (not limited by ion diffusion) and C_T is assumed to be the total capacitance, such as: C_T=C_PsC+C_EDL (S5) where C_PsC is the capacitance arising from Faradaic contributions. Figure S5C) and S5D) show, as an example, the intercept values of the linear regression for sample N8THC900-2 for equations S3 and S4, respectively.
