Safety Of Lithium Nickel Cobalt Aluminum Oxide Battery Packs In Transit Bus Applications, Timothy Cleary, Marc Serra Bosch, Jim Kreibick, Joel Anstrom

Mineta Transportation Institute Publications

The future of mass transportation is clearly moving toward the increased efficiency and greenhouse gas reduction of hybrid and electric vehicles. With the introduction of high-power/high-energy storage devices such as lithium ion battery systems serving as a key element in the system, valid safety and security concerns emerge. This is especially true when the attractive high-specific-energy and power-chemistry lithium nickel cobalt aluminum oxide (NCA) is used. This chemistry provides great performance but presents a safety and security risk when used in large quantities, such as for a large passenger bus. If triggered, the cell can completely fuel its own fire, …
