“…It is worth noting that there are other systems that also fulfill their properties in analyzing impedance spectra. Ivanishchev with co-authors [95][96][97][98][99] give such examples when the electrode surface was calculated. In the abovementioned works, the authors examine cathode behavior in this way, e.g., Li 3 V 2 (PO 4 ) 3 [100].…”

Hydrothermal crystallization was used to synthesize an advanced hybrid system containing titania and molybdenum disulfide (with a TiO2:MoS2 molar ratio of 1:1). The way in which the conditions of hydrothermal treatment (180 and 200 °C) and thermal treatment (500 °C) affect the physicochemical properties of the products was determined. A physicochemical analysis of the fabricated materials included the determination of the microstructure and morphology (scanning and transmission electron microscopy—SEM and TEM), crystalline structure (X-ray diffraction method—XRD), chemical surface composition (energy dispersive X-ray spectroscopy—EDS) and parameters of the porous structure (low-temperature N2 sorption), as well as the chemical surface concentration (X-ray photoelectron spectroscop—XPS). It is well known that lithium-ion batteries (LIBs) represent a renewable energy source and a type of energy storage device. The increased demand for energy means that new materials with higher energy and power densities continue to be the subject of investigation. The objective of this research was to obtain a new electrode (anode) component characterized by high work efficiency and good electrochemical properties. The synthesized TiO2-MoS2 material exhibited much better electrochemical stability than pure MoS2 (commercial), but with a specific capacity ca. 630 mAh/g at a current density of 100 mA/g.

“…Strong diffraction peaks can be observed in the XRD patterns, and all patterns are indexed as monoclinic structures with the P2 1 /n space group, which is consistent with previously reported results. [30][31][32] Moreover, no other impurity peaks are found, indicating that the synthesized materials are pure-phase and the carbon coated on the surface of the material is amorphous carbon. It has been proved in many related reports that the carbon lm coated on the surface of the materials can effectively improve the electronic conductivity and the utilization ratio of active substances, and enhance the rate performance of the materials.…”

“…Ecker et al [28] demonstrated good agreement between the diffusion values obtained by GITT and EIS. Further comparison of the techniques for characterising diffusion coefficients can be found in Deng and Lu [162] and Ivanishchev et al [163]. Applying titration techniques for SoC-dependent diffusivities is also particularly timeconsuming (ca.…”

The Doyle-Fuller-Newman framework is the most popular physics-based continuum-level description of the chemical and dynamical internal processes within operating lithium-ion-battery cells. With sufficient flexibility to model a wide range of battery designs and chemistries, the framework provides an effective balance between detail, needed to capture key microscopic mechanisms, and simplicity, needed to solve the governing equations at a relatively modest computational expense. Nevertheless, implementation requires values of numerous model parameters, whose ranges of applicability, estimation, and validation pose challenges. This article provides a critical review of the methods to measure or infer parameters for use within the isothermal DFN framework, discusses their advantages or disadvantages, and clarifies limitations attached to their practical application. Accompanying this discussion we provide a searchable database, available at www.liiondb.com, which aggregates many parameters and state functions for the standard Doyle-Fuller-Newman model that have been reported in the literature.
