A comparative investigation of aging effects on thermal runaway behavior of lithium-ion batteries

Thermal runaway is a major concern for the large-scale application of lithium-ion batteries. The thermal runaway performance of lithium-ion batteries not only depends on materials and cell design, but also changes with degradation. This paper presents a comparative investigation of the aging effects on the thermal runaway behavior of a large format lithium-ion battery. The batteries are first degraded under four different aging paths. The aging...
