Do cylindrical lithium-ion batteries have a thermal stability problem?
This work is motivated by the critical need to improve the thermal stability of cylindrical lithium-ion batteries, especially in electric vehicles and high-performance electronics, where overheating during rapid charging and high discharge rates can lead to thermal runaway and decreased lifespan.
Why are cylindrical lithium-ion batteries used in electric vehicles?
This study is particularly significant because cylindrical lithium-ion batteries are widely used in electric vehicles due to their high energy density and mechanical robustness. Various fin configurations are analyzed to optimize heat dissipation, effectively reducing peak temperatures during high discharge operations.
Can a liquid cooling model be used for lithium-ion batteries?
To overcome the current limitation where the coolant flow rate cannot be precisely aligned with the actual cooling requirements of batteries in thermal management systems, the researchers introduced a triple-step nonlinear approach. They developed a simplified thermal model for lithium-ion batteries employing liquid cooling.
How to manage the thermal challenges of lithium-ion batteries?
Additionally, the system should consider aspects such as thermal insulation to mitigate cold temperature effects and the prevention of thermal runaway events, emphasizing the importance of a comprehensive and multifaceted approach in managing the thermal challenges of lithium-ion batteries.
