Thank you for such wonderful explanation about the cell cooling coefficient effect on battery performance. any layman can get to understand about the process. once again thank you for your such hard research work.
We are trying to demonstrate that very large temperature gradients are required on some tab cooled cells because their tabs are not well designed for tab cooling. In this example, we highlight that the tabs must be kept 40degC below the maximum temperature of the cell in operation in order to remove the heat through the tabs at the required rate
In extreme cases, dendrite growth can cause an internal short-circuit within any lithium-ion battery. An internal short-circuit can lead to rapid heat generation from the battery and thermal runaway. Thermal runaway can also be caused by other events, for example through mechanical stress to the battery or through over-charging of the battery. Thermal runaway refers to any case where the battery self-heats and then rises very rapidly in temperature. We recently published a review on fire safety in lithium-ion batteries which is open access and can be found here: iopscience.iop.org/article/10.1149/1945-7111/aba8b9/meta

thanks for the video it was really helpful 😊
There is a mistake in min 3:15 approx. It says 40 degrees below, and it’s *Above

Why not use both TAB and surface cooling techniques?
It's expensive to do both. You may as well just use immersion cooling at that point. - Simon
What software do you use to create these animations in this video?
We hire an external animator to create the videos
Is thermal runaway the same as short circuit due to dendrite growth?
