Short Course on Lithium-ion Batteries: Fundamental Concepts, Heating Mechanisms and Simulation Techniques

Webcast Air Date: August 27th, 2016 Disciplines: Passive Thermal, Electrical Power This short course provides participants with an in-depth discussion on three aspects of lithium-ion (Li-ion) batteries that are relevant to the TFAWS community. First an understanding of Li-ion battery fundamentals is provided through a brief discussion centered around (a) the aerospace industry’s choice to use Li-ion batteries, (b) general performance characteristics and (c) electrochemical reaction basics. Secondly, Li-ion battery heat generation is discussed with respect to (a) Ohmic heating that occurs during nominal charge-discharge operations and (b) the heating mechanisms associated with a thermal runaway event. Understanding both heating mechanisms is critical to the development of effective thermal management systems. Lastly, this course will lead the participants through the basic construction process of a thermal model of a Li-ion battery assembly that is capable of simulating nominal heating and thermal runaway heating. The overall goal of the course is to provide participants with an in-depth understanding of both the fundamental and thermal aspects of Li-ion batteries.
