Lithium-ion batteries have higher energy and power densities, higher specific energy and power, and increased cycle life relative to other secondary battery chemistries. However, these batteries are inherently thermally unstable; despite decades of efforts to mitigate the associated safety hazards, events continue to occur in a wide range of applications. Fundamentally, new approaches are needed to prevent these events before they become dangerous without adversely impacting weight and volume.

This presentation will briefly overview the essential mechanisms associated with thermal runaway of lithium cells and packs, as well as safety mitigation strategies; ranging from cell chemical approaches to pack level management methods. In addition to discussing the benefits and drawbacks of these approaches, several new methods that have the potential to dramatically improve safety of large lithium-ion packs will be presented.

Noncredit courses do not produce academic credit nor appear on a Colorado State University academic transcript.
