Publication number: 20240119323Abstract: One or more embodiments of the present description provide a method and device for risk prediction of thermal runaway in LIB. The method includes: acquiring knowledge of a mechanism for thermal runaway in LIB; describing an evolution process of thermal runaway in LIB by adopting a fault tree; mapping a fault tree structure to a dynamic Bayesian network model for thermal runaway in LIB to obtain quantitative results of a risk of thermal runaway in LIB; and taking the quantitative results of a dynamic Bayesian network as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway. By using the method in the present embodiment, an evolution trend of battery thermal runaway can be predicted by fusing multiple thermal runaway causes and multi-source data, and thus, the prediction results are relatively accurate.Type: ApplicationFiled: May 17, 2023Publication date: April 11, 2024Applicant: Beijing Institute of TechnologyInventors: Huixing MENG, Qiaoqiao YANG, Zhiming YIN, Cheng WANG, Te HAN, Jinduo XING

The magnetic tunnel junction includes: a spin-orbit coupling layer, a ferromagnetic free layer, a barrier tunneling layer, a ferromagnetic reference layer, three local magnetic domain wall pinning centers and domain wall nucleation centers. An antisymmetric exchange interaction is modulated, and the magnetic domain wall pinning centers are embedded in an interface between a heavy metal and the ferromagnetic free layer. The magnetic domain wall nucleation centers are at two ends of the ferromagnetic free layer. A current pulse flows through the spin-orbit coupling layer to generate a spin current and the spin current is injected into the ferromagnetic free layer. Under a control of all-electrical controlled, an effective field of a spin-orbit torque drives domain wall to move and displace.Type: ApplicationFiled: January 21, 2021Publication date: February 29, 2024Inventors: Huai LIN, Guozhong XING, Zuheng WU, Long LIU, Di WANG, Cheng LU, Peiwen ZHANG, Changqing XIE, Ling LI, Ming LIU
