摘要： To provide a molten salt battery which is highly safe and has long charge/discharge cycle life. The molten salt battery of the present invention includes a negative electrode 1 in which a negative electrode active material 12 is predominantly composed of carbon such as hard carbon. The negative electrode active material 12 is surface-treated for imparting hydrophilicity to the negative electrode active material 12 to improve the affinity for the molten salt. Further, a transition metal such as iron is added to the negative electrode active material 12 predominantly composed of hard carbon in order to enhance the affinity for the active material. The molten salt battery has higher safety in production and use and longer charge/discharge cycle life than conventional molten salt batteries using metallic sodium as an electrode.

摘要： A separator of a molten salt battery made of a porous resin sheet. The separator is improved in wettability to a molten salt by giving hydrophilicity to the resin sheet. In the case of a fluororesin sheet, the sheet is impregnated with water, and irradiated with ultraviolet rays so that C—F bonds in the fluororesin are cleaved and the resultant reacts with water to generate hydrophilic groups, such as OH groups, in each surface layer thereof. The separator gains hydrophilicity through the hydrophilic groups. The separator made of the resin can be made into a bag form. In a molten salt battery having the bag-form separator, the growth of a dendrite is prevented.
