Calculating asymptotic expansion of Eq. (1) over Ω→∞, and keeping the single non-vanishing term, we get the high-frequency CCL resistivity ZCCL [14]: = + Z l k(1 )CCL t p (6) Taking into account Eq. (4) and rewriting Eq. (6) as = + Z l l 1 1 / 1 /CCL t p t e (7) we see that the CCL itself exhibits a “high-frequency” (ohmic) re- sistivity, which equals to the electronic and ionic resistivities connected in parallel.
