A Modelica library for Thermal-Runaway Propagation in Lithium-Ion Batteries

Linköping Electronic Conference Proceedings, 2021
Based on the Thermal Runaway (TR) experiments con-ducted in our laboratory a simple method of describ-ing a battery’s thermal behaviour was developed.Inthe approach - which we callsimple tracing method-the temperature rate measurement from Accelerating RateCalorimetry (ARC) during a TR experiment is approxi-mated to determine the thermal behaviour of ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Experimental study on the thermal runaway and its propagation of a lithium-ion traction battery with NCM cathode under thermal abuse

工程科学学报, 2021
Traction battery is the core component of the electric vehicle. To obtain longer driving ranges, conventional lithium-ion batteries with LiMn2O4, LiCoO2, and LiFePO4 cathodes were gradually replaced by LiNixCoyMn1−x−yO2 batteries.
