1. An electrochemical energy storage device comprising:
a first electrode including a first active material;
a second electrode including a second active material different in composition from the first active material; and
a non-aqueous electrolyte interposed between the first electrode and the second electrode, wherein:
the first active material includes a first metal salt having a first polyatomic anion and a first metal ion, the first metal salt exhibiting oxidation-reduction reaction involving reversible release and acceptance of the first polyatomic anion,
the non-aqueous electrolyte has electrical conductivity via the first polyatomic anion acting as a carrier,
the first polyatomic anion includes fluorocomplex ions having boron as nucleus, and
the first metal ion includes at least one selected from the group consisting of cations of Fe, Cu and Bi.
