Abstract
An air battery system has a sealed air battery cell () having: an air electrode having an air electrode layer () containing a conductive material and an air electrode power collector () for collecting electric power from the air electrode layer; a negative electrode having a negative electrode layer () containing an negative electrode active material that adsorbs and releases metal ions and a negative electrode power collector () for collecting electric power from the negative electrode layer; a separator () provided between the air electrode layer and the negative electrode layer; and a sealed air battery case (). The air battery system also has a depressurization portion () that reduces the internal pressure of the sealed air battery cell to below the atmospheric pressure.
