“…Once validated for a given system, physical models can be extremely useful in predicting cell behaviour under different cycling conditions, thereby saving time and cost compared with experimental testing alone. Physical modelling of bulk ASBs with porous cathodes is in its early stages but, when combined with experiment as for thin-film batteries, [60][61][62] is likely to yield important fundamental understanding of these systems. Where cell information (chemistry, physical dimensions, etc.)…”

“…Full cell battery models have been constructed in this way, with ECM fitting of experimental EIS data used to parameterize and validate the physical model. [60][61][62] Such 1D modelling is now readily available in commercial software packages, e. g. COMSOL Multiphysics. Further, 3D physical models of ASBs can make use of experimentallymeasured microstructural information to simulate high-capacity thin-film batteries [63] and bulk devices using porous solid-state electrodes.…”

Electrochemical Impedance Spectroscopy for All‐Solid‐State Batteries: Theory, Methods and Future Outlook

Electrochemical impedance spectroscopy (EIS) is widely used to probe the physical and chemical processes in lithium (Li)-ion batteries (LiBs). The key parameters include state-of-charge, rate capacity or power fade, degradation and temperature dependence, which are needed to inform battery management systems as well as for quality assurance and monitoring. All-solid-state batteries using a solid-state electrolyte (SE), promise greater energy densities via a Li metal anode as well as enhanced safety, but their development is in its nascent stages and the EIS measurement, cell set-up and modelling approach can be vastly different for various SE chemistries and cell configurations. This review aims to condense the current knowledge of EIS in the context of state-of-the-art solid-state electrolytes and batteries, with a view to advancing their scale-up from the laboratory to commercial deployment. Experimental and modelling best practices are highlighted, as well as emerging impedance methods for conventional LiBs as a guide for opportunities in the solid-state.

“…It is noticed that the PDE model [18] for developing the ROMs in [19]- [21] was established for specific thinfilm ASSBs where many internal phenomena can be ignored. However, most recent works [22], [23] have demonstrated the importance of considering the effects of concentrationdependent diffusion coefficient and ionic migration behavior in the positive electrode, which can significantly influence the charging/discharging capabilities of new ASSBs with wide positive electrodes. For example, it shows in [18] that a thinfilm ASSB cell with a 0.32 µm positive electrode can readily sustain 51C constant current discharge, whereas in [23], an ASSB with a much wider electrode (8.08 µm) is shown to be only suitable for up to 4C-6C discharge current rate, in which condition significant nonuniformity can be observed in the ionic diffusion properties in the positive electrode.…”

Considered as one of the ultimate energy storage technologies for electrified transportation, the emerging all-solidstate batteries (ASSBs) have attracted immense attention due to their superior thermal stability, increased power and energy densities, and prolonged cycle life. To achieve the expected high performance, practical applications of ASSBs require accurate and computationally efficient models for the design and implementation of many onboard management algorithms, so that the ASSB safety, health, and cycling performance can be optimized under a wide range of operating conditions. A controloriented modeling framework is thus established in this work by systematically simplifying a rigorous partial differential equation (PDE) based model of the ASSBs developed from underlying electrochemical principles. Specifically, partial fraction expansion and moment matching are used to obtain ordinary differential equation based reduced-order models (ROMs). By expressing the models in a canonical circuit form, excellent properties for control design such as structural simplicity and full observability are revealed. Compared to the original PDE model, the developed ROMs have demonstrated high fidelity at significantly improved computational efficiency. Extensive comparisons have also been conducted to verify its superiority to the prevailing models due to the consideration of concentration-dependent diffusion and migration. Such ROMs can thus be used for advanced control design in future intelligent management systems of ASSBs.

Lithiation mechanism of antimony chalcogenides ( Sb ₂ X ₃ ; X = S, Se, Te) electrodes for high‐capacity all‐solid‐state Li‐ion battery

Summary All‐solid‐state Li‐ion batteries are considered as next‐generation batteries, which provide safer operation by replacing the flammable liquid electrolyte by solid electrolyte. Developing these batteries using high capacity anode materials is warranted with the increasing demand of the energy sector. Among all the anode materials, alloying‐type anode materials are very attractive due to their high gravimetric as well as volumetric capacities, but they show large volume expansion which can be buffered by mixing different materials. Herein, all‐solid‐state Li‐ion batteries were prepared using Sb chalcogenide composites as electrode materials, and the detailed electrochemical reaction mechanism for the lithiation/delithiation has been established using cyclic voltammetry (CV), electrochemical charge–discharge profiling, electrochemical impedance spectroscopy (EIS), X‐ray diffraction (XRD), and scanning electron microscopy (SEM). The lithiation reaction for all the composites was found to be conversion reaction in the first step (Sb↔ Li2X and Sb) followed by alloying reaction in the second step (Sb ↔ Li3Sb), which is similar to that for liquid electrolyte case. All the composites showed the high volumetric capacity of >4000 mAh/cm3 in the first cycle, which reduced down to ~1500‐2000 mAh/cm3 after 100 cycles. This 50% retained capacity is higher in comparison to conventional carbon electrode as well as previously reported works on similar materials. The coulombic efficiency for all the composites was found nearly 99% after initial 10 cycles. The highest energy density was found as 344 Wh/kg for Sb2S3 composite after 100 cycles (765 Wh/kg in the first cycle), which nearly equals to the target values and makes these composites suitable for the future Li‐ion battery.
