Abstract
Disclosed is a high-capacity electrochemical energy storage device in which a conversion reaction proceeds as the oxidation-reduction reaction, and the separation (hysteresis) between the electrode potentials for oxidation and reduction is small. The electrochemical energy storage device includes a first electrode including a first active material, a second electrode including a second active material, and a non-aqueous electrolyte interposed between the first and second electrodes. At least one of the first and second active materials is a metal salt having a polyatomic anion and a metal ion, and the metal salt is capable of oxidation-reduction reaction involving reversible release and acceptance of the polyatomic anion.
