Prevent 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 ...
متن کاملThermal Runaway: Identifying the Cause of Rupture of Li‐Ion Batteries during Thermal Runaway (Adv. Sci. 1/2018)
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 h...
متن کاملa study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
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 کاملExperimental Study of Thermal Runaway Process of 18650 Lithium-Ion Battery
This study addresses the effects of the SOC (State of Charge) and the charging-discharging process on the thermal runaway of 18650 lithium-ion batteries. A series of experiments were conducted on an electric heating and testing apparatus. The experimental results indicate that 6 W is the critical heating power for 40% SOC. With a 20 W constant heating rate, the thermal runaway initial temperatu...
