摘要： A carbon material has at least either a peak related to diamond bonds, or a peak related to diamond-like bonds, appearing in a range of 1250 to 1400 cm−1 in a spectrum measured by Raman scattering spectrometry, and a full width at half maximum of a maximum peak, or each of full widths at half maximum of the maximum peak and a second largest peak, among peaks appearing in the range of 1250 to 1400 cm−1, has a signal less than 100 cm−1.

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.

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.
