“…Similarly individual electrode voltages can also be computed. As discussed in the above sections, SOC and battery terminal voltage can be calculated analytically using the single particle model unlike P2D (Pseudo 2 Dimensional) model [38,39] or DFN model [40] which would require solving 2 PDEs (Partial Differential Equations), 4 coupled ODEs (Ordinary Differential Equations) and the Butler-Volmer equation [41]. The complete set of equations pertaining to P2D [28] and SPM (Single Particle Model) derived in this work are tabulated in Table D.5 for comparison.…”

Sodium-ion batteries (SIBs) are emerging as promising energy storage systems. SIBs share similar chemistry and performance metrics with lithium-ion batteries (LIBs), the current workhorse energy storage technology. Abundant availability of sodium and its even distribution across the globe make SIBs a better alternative to LIBs. Electrochemical models enabling simulation of batteries help study performance and various parameters of batteries for a variety of operating conditions. Reduced order electrochemical models can be used to study batteries to obtain quick insights at a lower computational cost. In this work, we present a reduced order model for SIBs based on the single particle assumption. We validate the single particle model (SPM) by comparing the results with experimental data and predictions of detailed pseudo-two-dimensional (P2D) model. The SPM shows good accuracy in predicting voltage profiles over a range of discharge current densities. We further discuss the regime of operation where the SPM predictions deviate from that of the P2D model. Our study suggests that the SPM can be used as a viable alternative to the P2D model to design and test SIBs.

Rapid development of high-energy-density lithium-ion batteries (LIBs) enables the sufficient driving range of electric vehicles (EVs). However, the slow charging speed restricts the popularization of EVs. Commitment to fast-charging research is considered to be the key to advance the EVs strategy. This Review discusses the kinetic factors limiting the fast-charging capability at the material aspects, and summarizes the recent research strategies to achieve fast-charging performance of high-energy-density LIBs through electrode engineering, electrolyte design, and interface optimization. The increasingly important role of computational tools and advanced characterization techniques in fundamentally understanding the failure mechanism of LIBs is emphasized, and the analysis of the thermal runaway problem in the fast-charging process and the corresponding thermal optimization scheme is also involved to give the guidance for the more rational battery design. In view of these factors and strategies, some future perspectives for realizing high-performance fast-charging LIBs are proposed, which are expected to facilitate the large-scale application of fast-charging LIBs in EVs.

“…Among the various lithium salts, LiFSI was proved to have higher ionic conductivity by comparing with other normally used salts in LIBs [79–81] . Badwekar et al [82] . evaluated LiFSI and LiPF 6 by physics‐based electrochemical‐thermal mode, confirming the former one was a more suitable electrolyte for fast‐charge application to mitigate the thermal issues in cells.…”

Lithium-ion batteries (LIBs) with high energy density and fastcharge capability are urgently required for the ever-growing demands for electric vehicles and hybrid electric vehicles. To achieve this demand, as one of the important components, electrolytes are required to work well at a high voltage to fulfill the good performance of high energy density batteries and facilitate the fast-charge process. In this review, we mainly focus on the electrolytes design for LIBs under high-voltage and fast-charge conditions. The bottlenecks and the typical resolving strategies referring to lithium salts, solvents, solid electrolyte interface, additives and solvent structures in electrolytes are presented in detail. Finally, we propose the challenges regarding electrolytes design insight and inspiration for LIBs under the two conditions to give a better guide for the rationale design of the high energy density and fast-charge devices in the future applications.
