Thermal Runaway: Identifying the Cause of Rupture of Li‐Ion Batteries during Thermal Runaway (Adv. Sci. 1/2018)
نویسندگان
چکیده
At a critical temperature, active materials within Li-ion batteries break down, generating heat and gas. Thermal runaway occurs when this process accelerates after the temperature of the cell begins to rise, leading to hazardous failure mechanisms such as the cell bursting. In article number 1700369, Paul R. Shearing and co-workers use high-speed X-ray imaging to capture and characterize such high risk mechanisms in commercial cell designs.

Identifying the Cause of Rupture of Li‐Ion Batteries during Thermal Runaway
As the energy density of lithium-ion cells and batteries increases, controlling the outcomes of thermal runaway becomes more challenging. If the high rate of gas generation during thermal runaway is not adequately vented, commercial cell designs can rupture and explode, presenting serious safety concerns. Here, ultra-high-speed synchrotron X-ray imaging is used at >20 000 frames per second to c...
متن کاملMicrostructural Analysis of the Effects of Thermal Runaway on Li-Ion and Na-Ion Battery Electrodes
Thermal runaway is a phenomenon that occurs due to self-sustaining reactions within batteries at elevated temperatures resulting in catastrophic failure. Here, the thermal runaway process is studied for a Li-ion and Na-ion pouch cells of similar energy density (10.5 Wh, 12 Wh, respectively) using accelerating rate calorimetry (ARC). Both cells were constructed with a z-fold configuration, with ...

Prevention and mitigation of thermal runaway presents one of the greatest challenges for the safe operation of lithium-ion batteries. Here, we demonstrate for the first time the application of high-speed synchrotron X-ray computed tomography and radiography, in conjunction with thermal imaging, to track the evolution of internal structural damage and thermal behaviour during initiation and prop...
متن کاملPrevent thermal runaway of lithium-ion batteries with minichannel cooling
Thermal management on lithium-ion batteries is a crucial problem for the performance, lifetime, and safety of electric vehicles (EVs) and hybrid electric vehicles (HEVs). 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 minichannel cooling system designed at the battery module level and the ...
