Abstract: With increasing demand of clean energy, electrochemical energy storage technologies have attracted intensive research interest. In-situ electrochemical characterization with high temporal and spatial resolutions has become increasingly important for investigation of the electrochemical processes in close-to-real electrochemical energy storage devices. This paper reviews the progress of in-situ electrochemical characterization methodology, including in-situ transmission electron microscopy, synchrotron radiation X-ray spectroscopy, and sum frequency generation spectroscopy. The challenges facing in-situ electrochemical characterization and the prospects for further methodological development are presented.

Key words: electrochemistry, energy storage, in-situ characterization, transmission electron microscopy, synchrotron radiation, X-ray absorption spectroscopy, sum frequency generation spectroscopy
