Claim:
1. A containment vessel of a lithium-air battery in which a containment chamber for containing the lithium-air battery is formed, the containment vessel comprising: a first gas pipe communicated with the containment chamber, through which an inert gas is supplied to the containment chamber; a second gas pipe communicated with the containment chamber, through which the inert gas is exhausted from the containment chamber; a third gas pipe communicated with the lithium-air battery contained in the containment chamber, through which an air or oxygen gas is supplied to a cathode material of the lithium-air battery to perform a battery reaction of the air or oxygen gas with lithium ions in an electrolyte of the battery; a fourth gas pipe communicated with the lithium-air battery contained in the containment chamber, through which the air or oxygen gas is exhausted from the lithium-air battery; and a valve that is provided to the third gas pipe and controls opening and closing of communication to the containment chamber, wherein an inert gas supply source is provided to the first gas pipe, an air or oxygen gas supply source is provided to the third gas pipe, and by opening the valve provided to the third gas pipe, the inert gas in the containment vessel is provided to the cathode material of the lithium air battery through the third gas pipe.
