What is thermal dynamics in cylindrical Li-ion batteries?

Scientific Reports 15, Article number: 30830 (2025) Cite this article Thermal dynamics in cylindrical Li-ion batteries, governed by electrochemical heat generation, are critical to performance and safety in high-power applications such as electric vehicles and grid storage.

What is a thermal model for lithium-ion batteries?

Building upon our previously introduced framework, the thermal model is developed based on the multi-layer structure of cylindrical lithium-ion batteries, where each internal component is individually modeled to resolve its thermal behavior 33. For (i in overline {0,9} = {0,1,2,3,4,5,6,7,8,9}), the energy balance is expressed as:

How to ensure stable operation of lithium-ion battery under high ambient temperature?

To ensure the stable operation of lithium-ion battery under high ambient temperature with high discharge rate and long operating cycles, the phase change material (PCM) cooling with advantage in latent heat absorption and liquid cooling with advantage in heat removal are utilized and coupling optimized in this work.

Why do batteries have a low thermal conductivity?

But at the same time, the insulation layers with a low thermal conductivity prevent direct contact between batteries and cold plates. The low-temperature area at the end of batteries has been reduced, promoting the temperature uniformity of batteries. 3.3. Performance under continuous operating cycles
