Abstract:

Raman spectroscopy is a non-destructive analytical technique that provides detailed information on the chemical structure and molecular interactions of a sample. Insitu spectroelectrochemistry combined by spectroscopy and conventional electrochemical methods is a powerful technique for dynamically detecting the structure and phase composition of electrode materials. It has broad application prospects in energy storage and provides information on the micro-structure at the electrode interface. Raman spectroscopy can effectively characterize the change of various cathodic materials and complex ions in aluminum chloride-based electrolytes of rechargeable aluminum-ion batteries (AIBs) during the charging and discharging processes in situ. Combined with characterization techniques, such as XRD and XPS, Raman spectroscopy can effectively reveal the energy storage mechanism of rechargeable aluminum-ion batteries, including the study of electrolytes and electrode materials and insitu monitoring of electrode surface reactions. The study of the nature of electrode materials and interface structures can guide the optimal design of battery materials and microstructures, and the in-situ exploring of electrode surface reactions can help to conduct an in-depth study of the mechanism of electrode interface reactions for guiding the structural optimization of cathode materials and promoting the development of rechargeable aluminum-ion batteries.
