Can infrared fibre evanescent wave spectroscopy detect the evolution of battery chemistry?

To address this issue, we developed a diagnostic approach based on infrared fibre evanescent wave spectroscopy (IR-FEWS) that enables the evolution of battery chemistry to be tracked under real working conditions.

How can in situ spectroscopy support the development of new batteries?

In situ and operando infrared spectroscopies are powerful techniques to support the design of novel materials for batteries and the development of new battery systems. These techniques can support the study of batteries by identifying the formation of new species and monitoring electrochemical energy stability.

Can infrared fibre spectroscopy detect parasitic reactions in commercial batteries?

Nature Energy 7, 1128–1129 (2022) Cite this article Real-time tracking of the dynamic chemistry in commercial batteries by infrared fibre spectroscopy provides insight into the parasitic reactions that occur at the electrodes and in the electrolyte.

Can in situ FTIR spectroscopy be used to study lithium-ion batteries?

This review presents recent in situ FTIR spectroscopy contributions to lithium-ion batteries and other battery systems. It details the advantages of using in situ FTIR spectroscopy technique to study different battery systems and spectro-electrochemical cells.

Can optical fibre sensors decipher electrochemical processes inside a battery?

It is challenging to decipher electrochemical processes, especially at the molecular scale, inside a working battery. Here Tarascon and colleagues develop a technique that pairs optical fibre sensors with operando infrared spectroscopy to reveal the dynamic mechanisms of key processes in commercial Li-ion and Na-ion batteries.

Are FTIR characterization techniques used in battery research?

These characterization techniques have been improved and used for battery research in recent years. In this review, there are descriptions of some in situ and operando FTIR representative studies applied to battery systems describing the experimental approach, cell design, operation principles, and results.
