As lithium-ion batteries are now capable of handling higher charging and discharging power, ensuring their safety and implementing effective thermal management for the entire battery system has become crucial. Temperature significantly impacts the short-term and long-term performance of lithium-ion batteries.
Recently, Peng et al. has studied on the thermal safety of lithium-ion batteries with various cathode materials: a numerical study. A three-dimensional thermal model describing oven abuse processes of lithium-ion batteries was established to study the thermal stability and thermal safety of cathode materials.
Lei Sheng et al. conducted a study to characterize the thermal parameters of lithium-ion batteries with the goal of accurately predicting the temperature distribution in battery cell modules.
A key objective in the thermal design of lithium-ion batteries is to effectively mitigate heat generation and reduce the maximum temperature of battery cells under different conditions. Achieving these objectives simplifies the complexity of the thermal management system for lithium-ion batteries, leading to improved safety and performance.
One critical concern in the thermal modeling of lithium-ion batteries is the non-uniform temperature distributions within battery cells. To address this issue, various methods can be employed to achieve and demonstrate 3D thermal analysis, considering the spatial variations of temperature within the battery cell.
Overall, thermal modeling of lithium-ion batteries is a complex and critical aspect of battery research and development, enabling the study of their dynamic behavior and ensuring their suitability for various applications. Figure 3.
