However, the proliferation of such systems mainly powered by lithium-ion (Li-ion) batteries, introduces significant safety challenges – particularly the threat of ‘thermal runaway’. When thermal runaway occurs, the NCM Li-ion cell catches fire and much smoke and sparks are ejected from the rupture, while the LFP Li-ion cells just release a lot of white smoke; the NCM Li-ion cell is more hazardous and exhibits more severe thermal runaway reactions. This is usually more of a problem with high voltage parts and Schottkys since they have higher leakage to start with. Numerous methods have been proposed to mitigate the thermal runaway propagation (TRP), which can be divided into four categories: liquid cooling using cold plates, using thermal insulation material, integrating phase change material (PCM), and cooling using heat pipes, as summarized in Table 1. studied the influence of heating power Lithium-ion batteries (LIBs) are extensively utilized in electric vehicles (EVs), energy storage systems, and related fields due to their superior performance and high energy density.
