    摘要: Provided is a method for operating a molten salt battery having a sodium compound (NaCrO2) in a positive electrode and tin (Sn) in a negative electrode with a molten salt as an electrolytic solution. Although the operating temperature range of the molten salt battery is originally from 57° C. to 190° C., the molten salt battery is operated with an internal temperature thereof (temperature of electrodes and molten salt) set at from 98° C. to 190° C. to cause sodium to turn to a liquid phase. The sodium penetrates into a Sn—Na alloy micronized in the negative electrode, so that separation of the Sn—Na alloy is suppressed.

    摘要: A molten-salt battery includes a positive electrode including a positive-electrode active material that reversibly occludes and releases sodium, a negative electrode including a negative-electrode active material that reversibly occludes and releases sodium, a separator disposed between the positive electrode and the negative electrode, and a molten-salt electrolyte. The molten-salt electrolyte contains an ionic liquid in an amount of 90% by mass or more. The ionic liquid contains a first salt and a second salt. The first salt contains a sodium ion which is a first cation, and a first anion. The second salt contains an organic cation which is a second cation, and a second anion. The positive-electrode active material contains a composite oxide having a layered O3-type crystal structure and containing Na, Fe, and Co. An amount of Co relative to a total of Fe and Co contained in the composite oxide is 40 to 60 atomic percent.

    摘要: As a molten salt composition lacking a clear melting point and including a molten salt that can be suitably used as an electrolytic solution of a secondary battery, there is provided a molten salt composition including a mixture of two or more kinds of molten salts which can be used as an electrolytic solution of a secondary battery. Particularly, provided is a molten salt composition comprising two kinds of molten salts each having cations with ion diameters different from each other, composition ratio being set to a composition ratio within a range in which the molten salt composition lacks a melting point. Also provided is a secondary battery including the molten salt composition as an electrolytic solution, which can maintains an available state even when the temperature becomes low without rapidly becoming unavailable.
