Abstract
Lithium compounds such as lithium hydride (

) and anhydrous lithium hydroxide (

) have various applications in
industry but are highly reactive when exposed to moisture and

. These reactions create new molecular
compounds that degrade applications. Environmental conditions such as
temperature and moisture are examples of environmental conditions that
are of interest for these reactions. To interrogate the effects of
such weatherization, experiments were conducted in an environmental
chamber (Plas-Labs 890-THC glove box) employing a pulsed laser and an
echelle spectrograph in a novel single setup to conduct both Raman
spectroscopy and laser-induced breakdown spectroscopy (LIBS) in
tandem. These measurements in conjunction with data fusion and machine
learning techniques are used to develop training and testing of
environmental conditioning of Li compounds. Modeling of environmental
characterizations involving lithium-based compounds enabled by the
presented measurements and analytical techniques has significant
implications on industrial technologies, such as batteries, and other
nuclear applications.
