In this study, a phase-field model is developed to simulate the microstructure morphology evolution that occurs during solid electrolyte interphase (SEI) growth. Compared with other simulation methodologies, the phase-field method has been widely applied in the solidification modeling that has great relevance to SEI formation. The developed model can simulate SEI structure and morphology evolution, and can predict SEI thickness growth rate. X-ray photoelectron spectroscopy (XPS) experiments are performed to confirm the major SEI species as LiF, Li 2 O, ROLi, and ROCO 2 Li. Transmission electron microscopy (TEM) experiment is performed to present the SEI layer structures. The experiments reduce the complexity of the model development and provide validation to some extent. Fick's law and mass balance are applied to investigate lithium-ion concentration distributions and diffusion coefficients in different types of SEI layers predicted by the phase-field simulations. Simulation results show that lithium-ion diffusion coefficients between 298 K and 318 K are 1. 340-7.328 Lithium-ion batteries (LIBs) are widely used in many applications, such as cell phones, electric vehicles (EVs), and other energy storage modules. However, LIBs suffer from severe performance degradation due to undesired chemical reactions, 1 ageing, 2,3 corrosion, 4-6 compromised structural integrity, 7,8 and thermal runaway. 9-11 The degradation occurs during both calendar and cycling lifespans, and reduces the longevity of LIBs. Recently, much attention has been focused on LIB material decomposition, 12 e.g., the formation and growth of new components [13][14][15][16][17][18][19] due to undesired side reactions. 1,20 The main degradation mechanisms in LIBs vary with different active materials, 2 however, it is well known that a carbonaceous lithium-intercalation electrode in contact with electrolyte solution becomes covered by a passivation layer called a solid electrolyte interphase (SEI). While SEI can prevent the exfoliation of graphite materials and inhibit further electrolyte decomposition.21 SEI layer growth can also cause battery capacity fade and increase cell internal resistance. 17,[22][23][24][25][26] Therefore, the study of SEI plays a key role in battery degradation and other related performance improvement research. Many studies have been published in SEI computational and experimental studies, including but not limited to. [27][28][29][30] Many researchers have investigated SEI in LIBs in terms of structure, 7,8,29,31-33 formation and composition, 20,22,27 and thickness growth prediction and measurement. 15,16,34,35 SEI is believed to have a multilayered structure: a compact layer of inorganic components (e.g., LiF, Li 2 O) close to graphite electrode followed by a porous organic layer (e.g., ROLi, ROCO 2 Li) close to the electrolyte solution phase. 22,29,[31][32][33] The composition of SEI depends on the electrode materials and electrolyte composition.27 Broussely et al. investigated the mechanism of lithium loss in LIBs during ...

“…The SEI film on the negative electrode material is believed to be composed of two distinct layers. The modification of the negative electrode porosity due to SEI growth, was theoretically modelled by Sikha et al 15 More recently, Jannesari et al 16 modeled the variation of SEI thickness in the depth of the negative electrode of a Li-ion battery. This group demonstrated by simulations that improving the ionic conductivity significantly prolongs the lifetime of the battery owing to a uniform side reaction along the electrode.…”

International audienceIn this paper, an isothermal physics-based agingmodel from the literature is modified and extended to simulate both capacity and power fade of a commercial LiFePO4-graphite Li-ion battery. Compared to the isothermal reference, themechanism of porosity modification due to the Solid Electrolyte Interphase (SEI) film growth at the negative electrode is integrated in the present electrochemical and thermalmodel to establish theoretical correlations between capacity and power fade of the system. The agingmodel includes different contributions of the cell impedance increase such as the SEI film resistance and the electrolyte mass transport resistance due to the mitigation of the negative electrode porosity. Experimental databases from literature and specific experiments coupling endurance tests and Electrochemical Impedance Spectroscopy results, are used to calibrate and validate the correlated power and capacity loss simulations for both calendar and classic galvanostatic cycling operating conditions. The analysis of the experimental data points out that an additional possible aging mechanism such as cracking and fracture of the SEI layer could play an important role for cycling operating conditions and accelerate the electrochemical mechanisms. The impact of physical and design parameters on the power and capacity theoretical correlations are discussed. The limits of applicability of the present model are also discussed in this paper

“…3 show a comparison between the batteries capacity issued from both of the scenarios (continuous powercycling and combined power-cycling /calendar aging mode) respectively for experiments conducted at 55°C. From an electrochemical point of view, batteries performances degradation is a result of several simultaneous physic-chemical processes that occur within the electrode, electrode-electrolyte interface, and within the electrolyte [11], even in current collector referring to recent research [12]. Overall, the aging of lithium batteries still be a very complex phenomenon.…”

In this work, we highlight the performance recovery phenomenon when aging high-power lithium-ion batteries used in HEV application. This phenomenon consists in the increase on the battery capacity when we stop power-cycling. We demonstrate the dependency of this phenomenon on the stop-SOC value. Keeping battery at a fully discharged state potentially preserves a large amount of charge from the SEI-electrolyte interaction when they are in the positive electrode during rest time. Results from power cycling and combined, calendar/power cycling, aging of a 12 Ah-commercialized Lithium-ion battery at 55°C have been presented and obtained results have been discussed.
