Fig. 2: Horizontal temperature concavity through the hot spot is controlled by solid-state diffusion time.
From: Multiscale coupling of surface temperature with solid diffusion in large lithium-ion pouch cells
Insets: simulated surface-temperature profiles after 2500 s of square-wave cycling with 80 A applied-current amplitude and 100 s period with a 30% initial state of charge (4C-100s@30%), at various diffusion times td.
