Experimental investigation on thermal response behaviors of lithium-ion batteries subjected to nail penetration during dynamic discharge process

The thermal response of lithium-ion batteries subjected to mechanical abuse during active discharge remains insufficiently characterized. In this work, nail penetration experiments were conducted on 25 Ah prismatic LiFePO 4 cells while the cells were under 1C discharge at 100%, 9...

Suppression of thermal runaway in lithium-ion battery modules using zonal variable flow immersion cooling

The temperature sensitivity of lithium-ion battery modules is well recognized, and the requirements under normal operation and extreme thermal runaway conditions cannot be simultaneously satisfied by conventional thermal management strategies. A baffle-assisted zonal variable-flo...

Experimental and simulation study of a multichannel immersion cooling system for hot spot mitigation in energy storage batteries

The immersion battery thermal management (BTMS) system exhibits significant application potential in high-capacity energy storage systems. However, the inlet and outlet temperature effects of the coolant and the heat generation characteristics of lithium-ion batteries (LIBs) intr...
