A review of detecting Li plating on graphite anodes based on electrochemical methods

Abstract

Lithium plating, a highly detrimental process in lithium-ion batteries (LIBs), accelerates battery aging and induces rapid battery performance decline. Under extreme conditions, lithium plating can even compromise safety performance and lead to thermal runaway combustion and other consequences. Therefore, it is of great significance to detect and understand the internal mechanism of lithium plating. Electrochemical methods stand out among various detection approaches due to their convenience. In this review, we first discuss the formation mechanism of lithium plating metal and then introduce the corresponding detection methods by various electrochemical methods. Finally, we provide some prospects for future research on electrochemical detection methods for lithium plating.
