“…Therefore, it is meaningful to find a material with high ionic conductivity, such as Li 3 VO 4 and Li 2 ZrO 3 , to modify the cathodes. Li 2 ZrO 3 is a Li + conductor (about 10 –6 cm 2 ·s –1 ) that has satisfactory chemical stability . Lan et al prepared the Li 2 ZrO 3 -coated Ni-rich cathode that showed that 88.1% of the capacity remained after 200 cycles of charging/discharging at 0.5 C compared to 32.1% for the pristine cathode.…”

LiMn0.5Fe0.5PO4 cathodes have a high energy density but a poor rate and poor cycling performance. To this end, a series of N/S-doped LiMn0.5Fe0.5PO4/C composite cathodes modified with different contents of Li2ZrO3 were prepared by a solvothermal synthesis combined with calcination. The microstructure, chemical composition, and electrochemical properties are analyzed. Li2ZrO3 adsorbed on the LiMn0.5Fe0.5PO4 primary particles’ surface in an amorphous state and on spherical particles (5–10 nm). The cycling life and rate performance of the cathodes are improved by the modification of a moderate amount of Li2ZrO3. The LMFP/NS-C/LZO1 shows available capacities of 166.8 and 118.9 mAh·g–1 at 0.1 and 5 C, respectively. The LMFP/NS-C/LZO1 shows no capacity loss after 100 cycles of charging/discharging (1 C), and still has a high capacity retention of 92.0% after 1000 cycles of charging/discharging (5 C). The excellent cycling performance of the LMFP/NS-C/LZO1 can be attributed to the improvement of the cathode microstructure and the electrochemical kinetics and the inhibition of Mn2+ dissolution by the moderate Li2ZrO3 modification.

“…We assume that for those specific peaks, a third phase is contributing to the overall peak intensity. It is indeed possible that at those high Zr concentrations, a third stable phase ( h -Li 8 ZrO 6 R 3- m , a = 5.469 Å, and c = 15.353 Å) is formed during the synthesis . The h -Li 8 ZrO 6 reflections would overlap with those of m -Li 2 ZrO 3 , hindering a clear identification of each phase.…”

“…Although the latter polymorph was characterized by Quintana et al 28 at temperatures above 1100 °C, this metastable symmetry can also exist at temperatures below 800 °C. 29 , 30 The former extra phase belongs to the C /2 m space group ( a = 5.42401 Å, b = 9.02166 Å, c = 5.42021 Å and β = 112.59°) and the latter to the I 4/ amd space group ( a = 4.25582 Å, c = 9.01793 Å). 28 However, we were not able to index the phase of the two peaks present for the 5%-Zr-ss sample at 2.142 and 2.363 Å –1 .…”

Ni-rich layered oxides LiNi1–x–y Mn x Co y O2 (NMC811, x = 0.1 and y = 0.1) are considered promising cathode materials in lithium-ion batteries (LiBs) due to their high energy density. However, those suffer a severe capacity loss upon cycling at high delithiated states. The loss of performance over time can be retarded by Zr doping. Herein, a small amount of Zr is added to NMC811 material via two alternative pathways: during the formation of the transition metal (TM) hydroxide precursor at the co-precipitation step (0.1%-Zr-cp) and during the lithiation at the solid-state synthesis step (0.1%-Zr-ss). In this work, the crystallographic Zr uptake in both 0.1%-Zr-ss and 0.1%-Zr-cp is determined and quantified through synchrotron X-ray diffraction and X-ray absorption spectroscopy. We prove that the inclusion of Zr in the TM site for 0.1%-Zr-cp leads to an improvement of both specific capacity (156 vs 149 mAh/g) and capacity retention (85 vs 82%) upon 100 cycles compared to 0.1%-Zr-ss where the Zr does not diffuse into the active material and forms only an extra phase separated from the NMC811 particles.

“…Within this environmental context, the CO separation process possesses high interest during hydrogen (H 2 ) production, as most of this clean energetic vector is produced as gas mixtures containing both H 2 and CO coming from different catalytic processes. − Based on that, in the past years, different materials used as CO 2 chemisorbents − have been proposed as possible CO chemical captors. − In most of these cases, CO chemisorption implies an initial oxidation induced by an oxygen (O 2 ) flow present in the gas mixture. Nevertheless, a few of these materials have shown their ability to chemically trap CO even in the O 2 absence, i.e.…”

Scrutinizing the CO Chemical Capture Path in Li₂MnO₃ Samples with Different Microstructural Properties

Hydrothermal and ball-milling procedures combined with the solid-state reaction method were proposed as alternative synthesis routes to modify microstructural Li2MnO3 powders. All these materials were compared against Li2MnO3 prepared by following the solid-state reaction method only. To totally understand the effect of the synthesis routes proposed, the modified samples were structurally and microstructurally analyzed and subsequently subjected to the CO chemisorption process. Li2MnO3-modified samples exhibited important differences and improvements during the CO chemisorption process, in comparison to the powders obtained through the solid-state reaction method, associated with important variations on their microstructural features. Specifically, the sample prepared by the hydrothermal bottom-up approach and labeled as HSS700 showed the best CO chemisorption. This result was explained based on its crystal and particle sizes, morphology, and specific surface area. Moreover, the whole analysis performed on all the samples allowed one to determine that the solid–gas interphase controls the CO chemisorption over the CO-Li2MnO3 kinetics.
