Abstract
This disclosure relates to systems and methods for hydrogen sulfide mitigation. A battery cell or plurality of battery cells in a battery pack with a sulfur-containing lithium-based rechargeable battery component is presented. A monolith hydrolyzes hydrogen sulfide gas, precipitated from moisture exposure to the sulfur-based cathode, into sulfur dioxide and water, and releases the sulfur dioxide and water external to the battery cell.
Claims20
A battery cell comprising:
- a sulfur-containing lithium-based rechargeable battery;
- and
- a monolith configured to hydrolyze hydrogen sulfide gas, precipitated from moisture exposure to the cathode, into sulfur dioxide and water, and release the sulfur dioxide and water external to the sulfur-containing lithium-based rechargeable battery cell.
A battery pack comprising:
- a plurality of sulfur-containing lithium-based rechargeable battery cells;
- and
- a monolith configured to hydrolyze hydrogen sulfide gas, precipitated from moisture exposure to the plurality of battery cells, into sulfur dioxide and water, and release sulfur dioxide and water external to the battery pack.
A method comprising:
- directing hydrogen sulfide gas, precipitated from moisture exposure to a plurality of sulfur-containing lithium-based rechargeable battery cells, through channels of a monolith configured to hydrolyze the hydrogen sulfide gas into sulfur dioxide and water;
- and
- releasing the sulfur dioxide and water external to the plurality of sulfur-containing lithium-based rechargeable battery cells.
