  Further technological advancement of both lithium-ion and emerging battery
technologies can be catalyzed by an improved understanding of the chemistry and
working mechanisms of the solid electrolyte interphases (SEIs) that form at
electrochemically active battery interfaces. However, collecting and
interpreting spectroscopy results of SEIs is difficult for several reasons,
including the chemically diverse composition of SEIs. To address this
challenge, we herein present a vibrational spectroscopy and X-ray diffraction
data library of ten suggested SEI chemical constituents relevant to both
lithium-ion and emerging battery chemistries. The data library includes
attenuated total reflectance Fourier transform infrared spectroscopy, Raman
spectroscopy, and X-ray diffraction data, collected in inert atmospheres
afforded by custom designed sample holders. The data library presented in this
work (and online repository) alleviates challenges with locating related work
that is either diffusely spread throughout the literature, or is non-existent,
and provides energy storage researchers streamlined access to vital
SEI-relevant data that can catalyse future battery research efforts.
