    <dcterms:abstract><![CDATA[Several ZnO nanostructures such as nanosheets, nanotubes and quantum dots with Wurtzite structure have been prepared and studied as lithium-ion anode materials revealing that the increasing interface is a key aspect to improve their performance. To the best of our knowledge, up to now, there are no reports in the literature that deal directly with lithium-ion transport and charge transfer on ultrathin 2D ZnO exhibiting graphene-like and Wurtzite structures working as anode materials for lithium-ion batteries. Here, we present a DFT study on the lithiation of ultrathin 2D ZnO nanostructures including graphene-like (monolayer and bilayer) and Wurtzite (trilayer) structures. We focus on the ionic-electronic transport properties addressing the ionic transport through the different surfaces as well as charge transfer, equilibrium voltages, and work function variations due to lithiation for all systems. We reveal interesting features regarding how deep the reduction of Zn ions is still observed allowing more efficient charge transfer for graphene-like and Wurtzite systems working as anode material for a lithium-ion battery.]]></dcterms:abstract>

    <dcterms:abstract><![CDATA[This research focuses on the identification and quantification of lithium-ion battery degradation indicators at low temperatures. We studied the cycling aging of 18,650 commercial NMC lithium-ion batteries at 10 ◦C. For this purpose, we carried out life cycle tests and performed Galvanostatic Intermittent Titration Technique (GITT) tests in the voltage range for the charge and discharge processes for different States of Health (SoH). The diffusion time constant and the ohmic overpotential were determined from GITT for different SoH. As the batteries degrade both parameters increase. A degradation mechanism associated with faradaic effects (increase in ohmic drop overpotential) and a thermodynamic effect associated with changes in the active material (diffusional time constant) is observed. Furthermore, we performed Electrochemical Voltage Spectroscopy studies through Incremental Capacity (IC) curves. IC curves peaks and valleys are associated with battery phase transformations due to aging phenomena. Each peak has a unique peak height, area, and position associated with a degradation mode. This research focuses on the IC curves derived from the discharge capacities at 3A and OCP (Open Circuit Potential) to study the thermodynamic and faradaic effects separately. The peak at 3.6 V and 3.4 V for the 3A and OCP studies, respectively, is the main feature for the detection of the degradation mechanism. The valley in the OCP curves intensifies with the decrease in SoH and is shifted to lower potentials, an effect that is not observed in the 3A curves. So, we could associate this with thermodynamic effects, Loss of Lithium Inventory (LLI) and Loss of Active Material (LAM) of both the positive electrode and the negative electrode.]]></dcterms:abstract>

    <dcterms:abstract><![CDATA[Here, we report a synergistic in situ synthesis of lithium-ion poly (ethylene citrate) with embedded titania nanoparticles in which the esterification process itself triggered the hydrolysis of the titanium alkoxide precursor to form a promising fluorine-free lithium-ion solid polymer electrolyte. Structural characterization by means of X-ray diffraction, small angle X-ray scattering and also confocal Raman spectroscopy revealed the formation of the polyester with embedded titania nanoparticles in agreement with our Raman spectra simulation by means of DFT methodologies. Our theoretical modeling of the polyester also envisaged the interaction of lithium-ion via a tridentate coordination with oxygen atoms of carboxylate (&ndash;COO-) and ester (&ndash;COO&ndash;) groups. There is a slight increase in the degree of polymerization and thermal stability for our lithium-ion polyester with increasing titania nanoparticles concentration. In consequence, a two-order magnitude increase in the ionic conductivity was observed, yielding 1.74&times; 10&minus;4 S cm&minus;1 for a 20% weight fraction of titania nanoparticles. Thus, involving a novel approach based in the synergistic in situ preparation of lithium-ion poly (ethylene citrate) with titania nanoparticles, this procedure contributes to solve the many safety and environmental issues of the constitutive materials of lithium-ion solid polymer electrolytes.]]></dcterms:abstract>
