PROBLEM TO BE SOLVED: To provide a high energy density power storage device usable at high output. SOLUTION: The power storage device has a positive electrode containing a nitroxyl compound which turns into a N-oxo-ammonium cation partial substructure as shown by formula (I) in the oxidation state, and turns into a nitroxyl radical partial substructure as shown by formula (II) in the reduction state, and uses a reaction shown by reaction formula (A) that performs electron transfer between the the above two states as a positive electrode reaction, and has an electrolytic solution containing an ionic liquid having a quarternary ammonium cation partial substructure.
