Complete electrochemical transmission line model for conducting polymers

摘要

The small signal ac transport description of polarons and counterions and the corresponding Barker/Brumleve/Buck (BBB) transmission line model are extended by considering traps and also current generators due to steady-state conduction currents. The trap influence is discussed in the low frequency limit. For porous systems with double layer formation at the pore surface an averaging procedure leads to a modified transmission line model where the BBB type processes represent the hindrance of the charge transfer reaction.
