“…When operated under high-temperature environments and frequent discharging and charging rates, a sharp increase in battery temperature can occur, potentially leading to thermal runaway. [4][5][6] Uneven temperature fields have been documented to ultimately yield batteries that exhibit disparate aging properties and internal resistance, thereby further compromising their capacity and lifetime. [7] Therefore, urgent and significant battery thermal management (BTM) solutions are required to ensure battery operation at the optimal temperature range with a small temperature difference.…”

Liquid‐cooling techniques are commonly employed for battery thermal management (BTM) in commercial vehicles and energy storage applications, typically incorporating a cooling plate positioned beneath the casing of the battery pack. However, this heat transfer structural design results in smaller temperature drop in the terminal batteries located distantly from the plate, leading to an increased temperature difference. The integration of supplementary media into BTM systems holds the potential to enhance thermal management performance, thereby offering a viable solution to this issue. Herein, a fan is incorporated into the liquid‐cooling system to induce air circulation and augment convective heat transfer onto the battery surface. In the findings, it is revealed that the implementation of a reverse airflow path beneath the cooling plate result in a temperature decreasing rate of 0.59 K min−1, indicating a notable enhancement of 23% compared to solely employing a liquid‐cooling configuration. In the results, it is demonstrated that 1) reducing the inlet temperature can effectively enhance the rate of temperature reduction and 2) increasing the fan speed can reduce the temperature difference and promote temperature uniformity. In conclusion, in this present study, comprehensive guidelines and references are provided for the future design of BTM.

Li-ion batteries play a key role in energy storage and conversion in engineering systems such as electric vehicles and grid energy storage, with critical impact on electrification and storage of renewable energy. A key unresolved technological challenge in Li-ion batteries pertains to thermal runaway initiation and propagation in a battery pack, which can lead to subsequent fire and explosion. Despite significant past work, there remains a critical need to understand how thermal runaway propagates in a pack. This work presents a comprehensive investigation of the effect of radiative heat transfer on thermal runaway propagation. Radiation can be important when a battery is exposed to adjacent heat and fire sources, as well as in thermal runaway propagation from one hot cell to another. A theoretical radiative heat transfer model based on view factor theory is developed. Calculations based on this model for a simple 2D cylinder-to-cylinder geometry are found to be in very good agreement with analytical expressions. Radiation-induced thermal runaway propagation between two cylindrical 18650 batteries is evaluated. It is shown that radiation may play a key role in thermal runaway propagation, depending strongly on the triggering temperature. It is found that radiative effects in thermal runaway propagation exhibit both nonlinear and non-monotonic characteristics. At high temperatures, thermal runaway is triggered rapidly in the region close to the battery surface, where the chemical reactions are strongly coupled, and radiation plays a dominant role. In contrast, at lower temperatures, thermal runaway is triggered much more slowly and towards the core of the cell, where some chemical reactions may be decoupled, and pre-runaway chemical heat release plays an increasingly important role. The results presented here suggest that radiation can either facilitate or mitigate thermal runaway. The net radiation heat flux has a cross-over instant, beyond which radiation starts to retard thermal runaway. Additionally, the blocking effect in radiative heat transfer between cells arranged in equal-spacing homogenous or orthogonal arrangements in a battery pack is investigated, along with the effect of the hot spot size. Results from this work help understand the role of radiation in thermal runaway propagation and provide useful insights into the thermal runaway control and design of safe Li-ion battery packs.
