Abstract
A metal air battery includes an air purification module which communicates fluid to a battery cell module, purifies air flowing from an outside, and supplies the purified air to the battery cell module. The air purification module includes: a first air purifier which filters a first impurity of a plurality of impurities in the air flowing from the outside; and a second air purifier which filters a second impurity of the plurality of impurities, which is different from the first impurity.
Claims25
A metal air battery comprising:
- a battery cell module which generates electricity using oxidation and deoxidation of metal;
- and
- an air purification module which communicates fluid to the battery cell module, purifies air flowing from an outside, and supplies the purified air to the battery cell module,
- wherein the air purification module comprises:
- a first air purifier which filters a first impurity of a plurality of impurities in the air flowing from the outside;
- and
- a second air purifier which filters a second impurity of the plurality of impurities, which is different from the first impurity,
- a concentration detector which detects a concentration of at least one of the plurality of impurities in the air flowing from the outside;
- and
- a controller which controls operations of the first and second air purifiers based on information detected by the concentration detector,
- wherein the controller controls first electric power for the first air purifier based on the information detected by the concentration detector, and
- the controller controls second electric power for the second air purifier based on the controlled first electric power for the first air purifier.
