Heat generation in lithium-ion batteries is a complex phenomenon involving various electrochemical, physical, and chemical processes, which can be categorized into reversible and irreversible heat generation.
As the temperature rises, the thermal activity within the battery becomes more pronounced. At 40 °C, heat generation shows a more pronounced exothermic behavior during both charge and discharge cycles. The transition from endothermic to exothermic heat generation during charging occurs more rapidly than at lower temperatures.
As the temperature increases, the heat generation during charge and discharge becomes more pronounced, influencing the battery's efficiency, longevity, and safety. Fig. 3 compares heat generation profiles for lithium-ion batteries operating at two charge rates, 0.5C and 1C, measured at 30 °C.
To address this, advanced thermal management systems, such as phase change materials, liquid cooling, and high-performance heat sinks, 29 can be implemented to dissipate excess heat efficiently. In addition, battery designs that promote uniform temperature distribution and use materials with higher thermal stability can help reduce thermal risks.
This study highlights the critical importance of thermal management in lithium-ion batteries, focusing on heat generation mechanisms in commercial 18 650 lithium-ion battery cells.
It shows that reversible heat from entropy changes irreversible heat from ohmic losses, and charge transfer resistance significantly affects battery performance, safety, and lifespan. Elevated temperatures increase heat generation, accelerating capacity degradation and aging, with thermal runaway risks.
