摘要： A lithium-air battery system having a hermetic structure is provided and eliminates the need to be charged with additional oxygen gas. The system includes a lithium-air battery and an oxygen bombe that stores oxygen gas participating in a lithium-oxygen reaction. A first MFC adjusts a flow rate of oxygen gas supplied from the oxygen bombe to lithium-air battery cells. A blower repeatedly supplies oxygen gas flowing from the first MFC into the lithium-air battery cells. A compressor compresses oxygen generated from the lithium-air battery cells and passes through a second MFC, to a high pressure state to charge the oxygen bombe with the compressed oxygen during a charge operation. The second MFC adjusts a flow rate when oxygen gas generated from the lithium-air battery cells is supplied to the compressor during the charge operation. Additionally, an external power source supplies electric power to the compressor to charge the oxygen bombe.
