RESULTS AND DISCUSSION Figure 1 shows the XRD patterns for the hydration process of anhydrous LiOH, which was obtained by drying the LiOH· H 2 O at 150 °C. The XRD patterns of LiOH·H 2 O, LiOH,...

Figure 1 illustrates the X-ray diffraction pattern of the two types of LiOH ⋅ H 2 O crystals studied in this research. Differences for θ = 23.5° and 30.5° are observed.

In this study, we focused on the hydration reaction and dehydration process of LiOH at the pure vapor condition. The pressure–temperature diagram of LiOH equilibrium was measured.

Nov 24, 2021 · The hydration process of the anhydrous LiOH, which was obtained by drying the LiOH·H 2 O at 150 °C for 24 h, under ambient conditions was analyzed the XRD measurements. The XRD patterns were obtained at a scan rate of 10°/min to avoid the formation of hydrate species during the measurements.

Oct 1, 2017 · The effects of temperature on the conversion of Li 2 CO 3 to LiOH in a Ca(OH) 2 suspension were investigated. Li 2 CO 3 microplates were used as the Li source. The results showed that Li 2 CO 3 was converted to LiOH via in situ ion-exchange and dissolution–precipitation routes.

The infrared spectrum of a thin path of solid LiOH and LiOH·H 2 O (undeuterated, partially deuterated, and completely deuterated) has been observed. The spectra indicate that both hydrogens from each water molecule are used to form strong hydrogen bonds in the hydrate.

Sep 1, 1999 · The principal aim of this paper is to study the processes occurring during the extraction of the residual LiOH, more specifically the chemical delithiation of LiNiO 2 and its effect on the XRD characteristics and electrochemical behaviour.

Oct 23, 2017 · New battery chemistries based on LiOH, rather than Li 2 O 2, have been recently reported in systems with added water, one using a soluble additive LiI and the other using solid Ru catalysts. Here, the focus is on the mechanism of Ru-catalyzed LiOH chemistry.

By virtue of spray drying, a continuous nano LiOH∙H 2 O layer with low crystallinity is successfully coated on the surface of the GaLaZr precursor particles. Revealed by 2D Raman mapping and TEM, the intimate contact and uniform mixing have been realized between LiOH∙H 2 O and GaLaZr precursor.

Operando X-ray diffraction proves the cyclic formation and decomposition of the LiOH crystallites in the presence of LiI over multiple cycles, and the structural evolution provides key information for understanding and improving these highly relevant electrochemical systems.
