Abstract
Electrochemical Raman spectroscopy is an essential in-situ fingerprint spectroscopic analysis technique with advantages.This powerful tool is widely used in real-time studies of bulk and interfacial processes in various electrochemical systems.With the development of the lithium-ion battery field,the traditional carbon-based anode falls short of the burgeoning demand for enhanced performance.Silicon-based materials and transition metal oxides have garnered considerable attention as alternative materials of anodes,though further refinements are still necessary.Electrochemical Raman technique can reveal the changes in the electrode materials during the electrochemical process,which helps to guide the optimization of electrode materials.This paper commences with a principled exploration of Raman spectroscopy,delving into its inherent synergistic advantages when coupled with electrochemistry.It proceeds to showcase its application within the realm of anode material research.In addition,the paper undertakes a critical analysis of the challenges faced by electrochemical Raman spectroscopy in the context of lithium-ion battery research,and also offers an optimistic outlook into the future development trends of this indispensable technology.
