In recent years, in order to promote the green and low-carbon transformation of transportation, the pilot of all-electric inland container ships has been widely promoted [1].These ships are equipped with containerized energy storage battery systems, employing a "plug-and-play" battery swapping mode that completes a single exchange operation in just 10 to 20 min [2].
It is highly meaningful to stop charge or discharge process at such temperatures, which is protective for LMBs to minimize the thermal energy releasing at an earlier stage of thermal runaway.
The magnitude of the impact of electrode heterogeneity on thermal runaway induced by overcharging also likely differs with differing H values. For instance, electrodes with smaller H values may exert less effect on the shifting of the timepoint when thermal runaway is triggered.
The authors found that high charging rate and room temperature rise would increase thermal runaway risks, while aging could decrease thermal runaway risks. Also, the connection method of battery cells will influence thermal runaway characteristics .
This study investigated thermal runaway behaviors related to the heterogeneity characteristics of cathode electrodes in LIBs, using virtual simulation. Research on thermal runaway contributes to a better understanding and enhancement of the safety of LIBs. This is of significant importance to further expanding the applications of these batteries.
An overlay of the voltage and cell temperature during overcharge thermal runaway is shown in Figure 10. The cell voltage increased with the overcharging process until it reached a voltage plateau, then decreased slightly, and suddenly spiked again as thermal runaway occurred. Overcharging thermal runaway voltage a) and cell temperature b).
Among many electrochemical energy storage technologies, lithium batteries (Li-ion, Li–S, and Li–air batteries) can be the first choice for energy storage due to their high energy density. At present, Li-ion batteries have entered the stage of commercial application and will be the primary electrochemical energy storage technology in the future.

Our results indicate that decreasing porosity heterogeneity at the cathode may delay thermal runaway, owing to the heterogeneous impact on particle diffusion behaviors and the side reaction rate. Lithium-ion batteries (LIBs) are widely used in consumer electronics—including smart equipment, electronic bikes, medical devices, and telecommunication.
For instance, defective acceptance of dynamic charge and severe electrode sulfation with a negative charge under elevated restricted rate of charge (HRPSoC) conditions cause premature hydrogen release and water depletion in hybrid electric vehicles.
