<P>PROBLEM TO BE SOLVED: To further improve an electricity storage quantity per unit weight of a positive electrode. <P>SOLUTION: In a storage device, electrolyte contains nitroxy compound configuring a nitroxy cation structure in an oxidization state and a nitroxy radial structure in a reduced state, and a negative pole 16 contains metallic lithium, and a positive pole 20 contains carbon materials having a sulfo-group exchangeable with the nitroxy compound configuring the nitroxy cation structure. Thus, it is possible to improve the storage quantity per unit weight of the positive pole, in comparison with an electricity storage device using the electrolyte which does not contain the nitroxy compound or the electricity storage device using the positive pole constituted of carbon materials which do not have a sulfo group. <P>COPYRIGHT: (C)2009,JPO&INPIT |
