<P>PROBLEM TO BE SOLVED: To provide a power storage device which is superior in cycle characteristics in the power storage device using lithium or a lithium alloy as an active material for a negative electrode, and using a nitroxyl compound as an active material for a positive electrode. <P>SOLUTION: The power storage device is used, wherein the nitroxyl compound which is the active material for the positive electrode is dissolved in an electrolytic solution. With such a constitution, the nitroxyl compound dissolved in the electrolytic solution displays a catalytic effect on the surface of lithium or the lithium alloy, by which dendrite growth on the surface of the negative electrode is inhibited, and the cycle characteristics of the power storage device are improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
