Early Raman spectroscopic studies of Li-ion battery materials tended to avoid electrolytes containing lithium hexafluorophosphate (Li[PF 6]) spite Li[PF 6] being the most industrially relevant salt for practical systems, the salt can lead to large emission backgrounds under Raman spectroscopy (discussed in greater depth later) [6, 7, 8, 9].
In this review, the recent advances in the development of in situ Raman spectroscopy and electrochemical techniques and their application for the study of lithium-ion batteries are revisited. It is demonstrated that, during a

REVIEW PAPER In situ Raman spectroscopic–electrochemical studies of lithium-ion battery materials: a historical overview Victor Stancovski • Simona Badilescu Received: 13 July 2013/Accepted
With an emphasis on the electrode materials for lithium-ion (Li-ion) and sodium-ion (Na-ion) batteries, this study provides an overview of in-situ Raman techniques for
One of the most specific techniques, which is able to follow the phase changes in poorly crystallized electrode materials, makes use of Raman spectroscopy within the battery, i.e., in operando mode. Such an approach has been successful but is still limited by the rather signal-to-noise ratio of the spectroscopy. Herein, the operando Raman signal from the silicon anodes

Silicon (Si) is recognized as a promising candidate for next-generation lithium-ion batteries (LIBs) owing to its high theoretical specific capacity (~4200 mAh g−1), low working potential (<0.4 V vs. Li/Li+), and abundant reserves. However, several challenges, such as severe volumetric changes (>300%) during lithiation/delithiation, unstable solid–electrolyte interphase

In this contribution we describe a detailed Raman spectroscopic characterization of LiCoO 2 electrode materials. In the results and discussion section first the structure, then the resonance enhancement, and finally the spatially-resolved analysis and in situ analysis of powder LiCoO 2 electrode materials are described. The signal enhancement by resonance Raman

The massive fluorescence/emission signal observed in highly/fully lithiated LiC 6 by ungated ultra-fast laser-pulsed Raman and conventional CW Raman (Figure Figure3 3 c) ensures that it becomes difficult (or impossible) to reliably probe the high states of lithiation (i.e., state charge of graphite and the lithium inventory as a negative electrode) by these methods.
