Abstract
A lithium oxygen cell system (10) includes a battery cell (15), a containment vessel (106) having an air inlet conduit (114) and an air outlet conduit (112). An access control valve (101), a one way check valve (102), a H2O scrubber (103) and a CO2 scrubber (104) are mounted within inlet conduit. A one way check valve (107) and a forced air device (108) are mounted within outlet conduit. A charge controller (109) is coupled to battery and to the air device. The pair of one way check valves insure that the inside of the containment vessel (106) may be sealed. The system further includes a safety controller (111) coupled to an environmental sensor (110), and to control valve (101). When an unsafe temperature or pressure condition is detected, it closes control valve to shut down operation of the battery and thereby prevent a catastrophic event.
