Abstract: How to prevent thermal runaway and thermal spread effectively is important in the design of lithium-ion battery modules. In order to explore the control ability of different heat dissipation design on the thermal spread of lithium-ion battery module, taking lithium titanate battery modules as the experimental object, the thermal spread blocking ability of natural convection, surface liquid cooling, and tab forced air cooling were studied. Through comparison, it is found that the key to suppressing thermal spread effectively is to increase the resistance of the spreading path and improve the heat dissipation capacity. The blocking method of surface cooling is more direct, which can block thermal spread, and the effect is far better than that of tab cooling.
Key words: Lithium Titanate battery, thermal spread, thermal design, surface cooling, tab cooling
