Other spectroscopy characterization techniques, such as Raman and UV-vis spectroscopies (not addressed in this review), are also extremely useful and can render complementary information to FTIR spectroscopy. Fig. 11. Effects of how in situ and operando FTIR spectroscopy can support the research of specific battery systems.
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.
Improvements in mapping/imaging using FTIR and Raman—as well as progress on nano-micro FTIR spectroscopy, such as SINS—are necessary to spread this technique, which may highly contribute to the development of energy storage devices in the future.
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.
