EQCM for In-depth Study of Metal Anodes for Electrochemical Energy Storage

Electrochemical quartz crystal microbalance(EQCM)is a powerful tool to study the mass change and charge transfer during electrochemical process.The mass change on the electrode surface can be monitored with high precision and high sensitivity,making it possible to analyze the in-depth mechanism of electrode reactions.The application of metal anodes has exhibited great potential for the future energy storage devices for the elevated capacity.Herein,we review the research progress utilizing EQCM for metal anodes,including the deposition/dissolution process,the side reactions,the effect of additives,etc.Furthermore,we also put forward a perspective on research of the mechanism and performance improvement of metal anodes.
