    摘要： An active material for non-aqueous-system secondary battery according to the present invention is characterized in that it comprises a mixture of an alkali metal salt and a transition metal, and it carries out reversible oxidation-reduction by means of charging-discharging, oxidation-reduction in which an alkali metal is eliminated from a compound being made by reacting the alkali metal salt with the transition metal, and oxidation-reduction in which the alkali metal salt and the transition metal are reproduced from the compound into which the alkali metal has been inserted. It becomes feasible to make a non-aqueous-system secondary battery exhibit a higher capacity by using this active material for the non-aqueous-system secondary battery. Moreover, since the active material for non-aqueous-system secondary battery according to the present invention includes an alkali metal that works as electrolyte ions, another active material that is used for the counter electrode is not limited. For example, in a lithium-ion secondary battery, the safety upgrades because it is possible to forgo employing electrodes that include metallic lithium.
