In situ conductivity-potential profiles and cyclic voltammograms of an LiCoO2 thin film were obtained simultane-ously by using an interdigitated microarray electrode with a constant potential difference. The electronic conductivity of Li1-xCoO2 increased exponentially with potential during lithium extraction from 2.7 to 4.0 V. The conductivity changes drastically when very small amounts of Li (0<x<0.1) are extracted.
