“…The most important cases of the geometry and the relevant solutions of the diffusion task are considered in detail in our earlier papers [6,42,55]. Among them, for Li 3 V 2 (PO 4 ) 3 electrode, two geometries of diffusion space can be selected.…”

“…However, this problem cannot be solved without a detailed study of the transport properties of the compound and their correlation with structural and morphological parameters. Such works can be found in literature [5], among them, there is a recent work of our research group [6], in which the study of lithium ion transport in Li 3 V 2 (PO 4 ) 3 electrode was carried out using a combination of electrochemical methods-cyclic voltammetry and pulse chronoamperometry in PITT variant.…”

“…Subsequently, the theoretical relations have been developed in the works of several researchers. Montella et al [44][45][46][47][48][49][50] and Churikov et al [6,42,[51][52][53][54][55] independently proposed analytical solutions of ion transport task in intercalation electrode having slow kinetics of the transfer in surface layer and subsequently distributed these concepts to other cases of diffusion space geometry. Levi et al [28,35,[56][57][58][59][60][61][62][63][64] showed a decisive influence of the thermodynamic factors on the transport processes in the intercalation electrode, and modified the theory of PITT and GITT methods taking into account the sorption isotherm of the intercalation electrode, a general view of which can be described the most accurately by the Frumkin intercalation isotherm.…”

In order to establish the mechanism and to determine the parameters of lithium transport in electrodes based on lithium-vanadium phosphate (Li 3 V 2 (PO 4 ) 3 ), the kinetic model was designed and experimentally tested for joint analysis of electrochemical impedance (EIS), cyclic voltammetry ( C V ) , p u l s e c h r o n o a m p e r o m e t r y ( P I T T ) , a n d chronopotentiometry (GITT) data. It comprises the stages of sequential lithium-ion transfer in the surface layer and the bulk of electrode material's particles, including accumulation of lithium in the bulk. Transfer processes at both sites are of diffusion nature and differ significantly, both by temporal (characteristic time, τ) and kinetic (diffusion coefficient, D) constants. PITT data analysis provided the following D values for the predominantly lithiated and delithiated forms of the intercalation material: 10 −9 and 3 × 10 −10 cm 2 s −1 , respectively, for transfer in the bulk and 10 −12 cm 2 s −1 for transfer in the thin surface layer of material's particles. D values extracted from GITT data are in consistency with those obtained from PITT: 3.5-5.8 × 10 −10 and 0.9-5 × 10 −10 cm 2 s −1 (for the current and currentless mode, respectively). The D values obtained from EIS data were 5.5 × 10 −10 cm 2 s −1 for lithiated (at a potential of 3.5 V) and 2.3 × 10 −9 cm 2 s −1 for delithiated (at a potential 4.1 V) forms. CV evaluation gave close results: 3 × 10 −11 cm 2 s −1 for anodic and 3.4 × 10 −11 cm 2 s −1 for cathodic processes, respectively. The use of complex experimental measurement procedure for combined application of the EIS, PITT, and GITT methods allowed to obtain thermodynamic E,c dependence of Li 3 V 2 (PO 4 ) 3 electrode, which is not affected by polarization and heterogeneity of lithium concentration in the intercalate.

“…Material properties used in other cases were calculated based on experimental work in other studies. Finally for Case 5 the solid Li diffusion rate was decreased to 1.5 × 10 À16 m 2 /s based on values from experimental work by Ivanishchev et al [51]. For Case 2 the electrolyte thickness was reduced by half to 750 nm.…”

Summary The goal of the work presented here was to develop a simulation approach for studying the effects of materials and geometry on the performance of Li‐ion Solid State Batteries (SSB). Simulation provides the opportunity to explore, with ease, different material properties and cell geometries to optimize a Li‐ion SSB's performance. Simulations shown in this paper are time‐dependent and consider electrochemical reaction, heat transfer, the diffusion of Li‐ions and electrons in the electrolyte, and solid Li diffusion in the positive electrode. A 2D model was simulated and the results shown. The simulations were able to show discharge curves, heat flux, the concentration of Li‐ions, electrons, and solid Li at any time in the discharge cycle. Copyright © 2015 John Wiley & Sons, Ltd.
