Abstract
At present, industries such as electric vehicles, electric advanced air mobility, and power generation and storage markets are continuing to grow and are creating an increasing demand for advanced energy storage solutions. The lithium-ion battery technology is currently one of the best solutions for high energy density and high-power density storage. There are many aspects of the lithium-ion battery that need improvement for the adoption to be as rapid as infrastructure will allow. Some of these key aspects include understanding of the critical temperatures and mechanisms for thermal runaway failure, prediction techniques for estimating the thermal response during thermal runaway failure, and mitigation strategies for preventing propagation of thermal runaway within a lithium-ion battery system in case of a failure. This study explores the existing literature regarding mechanistic thermal runaway failure and the determination of the cell’s critical temperatures. This study also presents a coupled thermal and electrochemical model used for estimating the temperature response of a cell in thermal runaway. An analysis of heat transfer in the cell during failure was also performed and using the results of the analysis, mitigation strategies are proposed for preventing thermal runaway propagation within a lithium-ion battery system.
