Abstract
A secondary battery in which the difference between the voltage at the time of discharging and the voltage at the time of charging is small, ensuring good energy efficiency, and the charge/discharge life is long. Therefore, in order to attain the above-described object, a secondary battery containing a positive electrode, a negative electrode, and an electrolytic solution, wherein at least one of the positive electrode and the negative electrode contains, as the active material, at least one selected from the group consisting of a metal ion-containing fluoride, a metal oxide, a metal sulfide, a metal nitride, and a metal phosphide; the electrolytic solution contains an anion receptor; and the anion receptor forms a salt or a complex with an anion contained in the active material, thereby enabling the active material to dissolve in the electrolytic solution.
