Abstract
A F-type electrochemical cell, which is a lithium air battery, includes a positive electrode facing a negative electrode composed of metallic lithium with a separator provided therebetween in a casing. Air is capable of flow to the positive electrode. A nonaqueous electrolytic solution is charged into a space between the positive electrode and the negative electrode. At least one of the positive electrode and the nonaqueous electrolytic solution of the lithium air battery contains a compound having a stable radical skeleton. The compound also serves as a redox catalyst for oxygen.
