| Summary: | 碩士 === 國立臺北科技大學 === 製造科技研究所 === 106 === Thermal management on lithium-ion battery is a crucial problem for performance, capacity, lifetime, and safety of consumer electronics, energy storage systems, and electric vehicles. Fire and explosions can be triggered by thermal runaway if the temperature of the lithium-ion batteries is not maintained properly. This work describes a far infrared nano-composite material applied at the aluminum laminated film of lithium ion battery and the investigation on its efficacy on the mitigation of thermal runaway. High temperature oven and vertical heating press machine were employed to verify the internal short circuits, which in reality may be caused by high working temperature or manufacturing defects. Control group and experimental group were used to compare the yield rate optimization. Four test models were utilized to study thermal runaway: the heat convection test model, the heat conduction model, the upper heating of vertical heating press machine model, and upper with lower heating of vertical heating press machine model. It is concluded that far infrared nano-composite material coating can protect lithium ion batteries to occur thermal runaway.
