Abstract
A lithium-ion battery assembly includes a lithium-ion battery pack that produces exhaust gases under stress conditions. Characteristically, the exhaust gases includes carbon monoxide, hydrogen, and hydrocarbons. A catalyst system is in fluid communication with the exhaust gases. Advantageously, the catalyst system configured to promote breakdown of carbon monoxide, hydrogen, and hydrocarbons at temperatures greater than about 100° C.
Claims11
A lithium-ion battery assembly comprises:
- a lithium-ion battery pack that produces exhaust gases under stress conditions, the exhaust gases including carbon monoxide, hydrogen, and hydrocarbons;
- a housing into which the lithium-ion battery pack is positioned, the housing including a vent port that fluidly connects an interior of the housing to ambient atmosphere;
- and
- a catalyst system disposed in the vent port and in fluid communication with the exhaust gases vented from the housing, the exhaust gases including carbon monoxide, hydrogen, and hydrocarbons, wherein the oxidation catalyst system comprises palladium and/or copper dispersed on a cerium-zirconium oxide support and, in the presence of oxygen is configured to convert the carbon monoxide, hydrogen, and hydrocarbons to carbon dioxide and water at temperatures greater than about 100° C.
