“…Niculuta et al 48 deployed IR imaging to determine the surface temperature profile during discharge at different rates and used it to validate the 3D electrochemical model of a LFP cell. Bazinski et al 49 used it in conjunction with the lumped capacitance model to predict heat generation in a LFP pouch cell. Panchal 21 employed IR imaging to study hot spots and current concentration regions in the battery at various stages in battery cycling.…”

Safety is a major challenge plaguing the use of Li-ion batteries (LIBs) in electric vehicle (EV) applications. A wide range of operating conditions with varying temperatures and drive cycles can lead to battery abuse. A dangerous consequence of these abuses is thermal runaway (TR), an exponential increase in temperature inside the battery caused by the exothermic decomposition of the cell materials that leads to fire and explosion. It is imperative to develop methodologies to accurately predict and mitigate thermal runway. Sodium-ion batteries (SIBs) are inherently safer than LIBs. In addition to offering better safety, SIBs are gaining momentum due to the abundance and low cost of their raw materials compared to the limited lithium resources and high cost of elements such as cobalt, copper, and nickel used in LIBs. However, the challenge of low energy density impedes the maturation of sodium-ion technology to the same level as lithium-ion technology. There are additional challenges to the acceptability of sodium-ion batteries due to the poor sodium kinetics during insertion reactions, leading to rapid material degradation. Additionally, the higher solubility of the solid electrolyte interface (SEI) observed in the case of SIBs may lead to undesired side reactions, causing increased heat generation. This paper presents a comprehensive review of the heat-release mechanisms, their differences, and prediction methodologies for the two battery chemistries. Various experimental and modeling approaches for TR detection from the literature are reviewed. Future research directions toward the development of a battery management system (BMS) with the capability to identify the precursors to thermal runaway and implement mitigation strategies are also discussed.

“…2,3 Thermal management is a critical concern because LIBs generate a considerable amount of heat during operation, particularly for demanding application such as in the automotive industry. [4][5][6][7][8][9][10] This heat is generated due to the electrochemical processes occurring at the pore-scale in LIBs. 4,9,[11][12][13][14][15][16] Reversible heat is generated due to the material phase changes and therefore entropy change.…”

There is no universal and quantifiable standard to compare a given cell model’s capability to reject heat. The consequence of this is suboptimal cell designs because cell manufacturers do not have a metric to optimise. The Cell Cooling Coefficient for pouch cell tab cooling (CCC tabs ) defines a cell’s capability to reject heat from its tabs. However, surface cooling remains the thermal management approach of choice for automotive and other high-power applications. This study introduces a surface Cell Cooling Coefficient, CCC surf which is shown to be a fundamental property of a lithium-ion cell. CCC surf is found to be considerably larger than CCC tabs , and this is a trend anticipated for every pouch cell currently commercially available. However, surface cooling induces layer-to-layer nonuniformity which is strongly linked to reduced cell performance and reduced cell lifetime. Thus, the Cell Cooling Coefficient enables quantitative comparison of each cooling method. Further, a method is presented for using the Cell Cooling Coefficients to inform the optimal design of a battery pack thermal management system. In this manner, implementation of the Cell Cooling Coefficient can transform the industry, by minimising the requirement for computationally expensive modelling or time consuming experiments in the early stages of battery-pack design.
