Lithium-air battery system using vortex tube

A lithium-air battery system using a vortex tube, comprising:

• a lithium-air battery;
• a gas supply device configured to supply a reaction gas for electricity production to the lithium-air battery;
• the vortex tube disposed between the lithium-air battery and the gas supply device to divide the gas, supplied from the gas supply device, into a high-temperature gas and a low-temperature gas;
• a first 3-way valve disposed between the gas supply device and a compressed-air supply port formed in a main body of the vortex tube;
• and
• a second 3-way valve disposed on a side of a gas outlet and a cooling path outlet of the lithium-air battery,
• wherein the high-temperature gas, produced in the vortex tube, is supplied to the lithium-air battery, and simultaneously, the low-temperature gas is supplied to a cooling path in the lithium-air battery.
