Panchal et al. delved into a thermal analysis of lithium-ion batteries, revealing temperature fluctuations along the battery cell’s surface, particularly under high current rates. This phenomenon originated from significant heat dissipation driven by notable temperature gradients.
The interaction between temperature regulation and lithium-ion batteries is pivotal due to the intrinsic heat generation within these energy storage systems.
Thermal Characteristics of Lithium-Ion Batteries Lithium-ion batteries, known for their nonhomogeneous composition, exhibit diverse heating patterns on the surface of battery cells.
Simulations indicate that this innovative approach will effectively prolong the battery’s lifespan through temperature regulation. To reduce the temperature of lithium-ion batteries, T. Talluri et al. incorporated commercial phase change materials (PCMs) with different thermal properties.
The self-production of heat during operation can elevate the temperature of LIBs from inside. The transfer of heat from interior to exterior of batteries is difficult due to the multilayered structures and low coefficients of thermal conductivity of battery components , , .
A potential solution involves developing a dynamic, time-dependent heat generation model for lithium-ion batteries, incorporating data from battery calorimeters. This model could effectively address the challenge of non-uniform temperature distribution and heat generation on battery cell surfaces.
