Electrochemical doping is assumed to be limited by ion motion due to large mass in mixed ionic-electronic conductors. Here, the authors reveal in a typical polythiophene that electrochemical doping speeds are limited by poor hole transport at low doping levels, leading to much slower switching speeds than expected.
