What is it about?
The paper highlights the growing importance of thermal modeling for lithium-ion batteries due to safety concerns and optimal battery management. The paper presents initial results obtained from extending the electrothermal impedance spectroscopy (ETIS) measurement concept, which could facilitate future 2D and 3D battery thermal modeling without prior knowledge about a battery's properties.

Why is it important?
This paper implies that thermal modeling is essential for lithium-ion battery cells and packs as they become more energy dense and compact. The multidimensional ETIS concept can help with 2D and 3D battery cell/pack thermal design without requiring prior knowledge of battery properties, which can save time and money. However, more studies are needed to compare the accuracy of these models with real-time images during different current rates of charging/discharging.
Perspectives
The analysis and enhancement of the electrothermal impedance spectroscopy (ETIS) concept for estimating thermal properties in lithium-ion batteries. Preliminary investigations on applying ETIS to multi-point measurements, which could enable 2D and 3D battery cell thermal modeling without needing prior knowledge of a battery’s internal structure or composition.
