Revealing SEI Formation and Evolution at the Li Anode/Liquid Electrolyte Interface in Li-ion Batteries by in situ Fourier Transform Infrared Spectroscopy
… switching to LP57, Li₂CO₃ became the dominant SEI component. When the three electrolytes were cycled in the spectroelectrochemical cell, the SEI peaks continued to grow for the first 10 cycles. After the first 10 cycles, LEMC and Li₂CO₃ growth plateaued, indicating SEI stabilization. On the …

Study of Interfacial Chemical Reactions on Battery Electrodes Using Operando Imaging Techniques
… the quality of the solid-electrolyte interphase (SEI) determines the battery's performance. However, the understanding of SEI formation and evolution processes across the electrode interface is still limited due to the lack of in-situ characterization tools. Here, we study and image the local SEI …
