Scholarcy highlights

  • In situ conductivity‐potential profiles and cyclic voltammograms of an thin film were obtained simultaneously by using an interdigitated microarray electrode with a constant potential difference.
  • The electronic conductivity of increased exponentially with potential during lithium extraction from 2.7 to 4.0 V.
  • The conductivity changes drastically when very small amounts of Li () are extracted.
