| Abstract Scope |
The electrode-electrolyte interphase remains a poorly understood topic in Li-ion battery (LiB) research due to its intrinsic properties—complexity, high reactivity and continuous evolution—and its detailed and real-time analysis is a great challenge. Vibrational spectroscopy is a powerful tool for understanding the interfacial chemical reactions and the structural changes in an electrode, so the technique is used extensively by the battery community in their ex situ form. Developing in situ variants of the technique, however, can provide new insight and help to elucidate the failure mechanism in battery systems. Recently, we have developed in situ vibrational spectroscopic methods that show reproducible and reliable performance over multiple cycles in terms of both electrochemistry and spectroscopy, which enables us to monitor the surface chemistry and structural changes on/in the electrode. This is critical to gaining a fundamental and mechanistic understanding of the electrochemical performance of LiBs. |
