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.

摘要： Provided is a molten salt battery which can be stably charged and discharged. A separator 3 composed of a rectangular plate-shaped glass cloth and containing a molten salt is interposed between a positive electrode 1 and a negative electrode 2 having a rectangular plate shape to form a power generating element X. A battery container 5 is configured to be substantially rectangular parallelepiped-shaped. A non-flexible presser plate 4b pressed by a spring 4a arranged at a negative electrode 2 side in the battery container 5 substantially evenly disperses pressing force from the spring 4a and presses the negative electrode 2 downward. As a result of the reaction, a bottom wall 52 of the battery container presses the positive electrode 1 upward so that no dead space is generated even when a plurality of batteries are combined.

摘要： In a molten salt battery device, molten salt batteries are arranged in a container to cause a space to be present around the molten salt batteries, and a heating medium is filled into the space around the molten salt batteries. When an electrothermal heater is used to control the temperature of the heating medium through a temperature controlling section, the heating medium is caused to flow. Between the flowing heating medium and the molten salt batteries, heat is exchanged, whereby the molten salt battery device controls the temperature of the molten salt batteries. Since the molten salt batteries attain the heat exchange with the heating medium, which surrounds the batteries, the internal temperature thereof is evenly controlled. Moreover, the molten salt battery device makes it possible to lower the temperature of the heating medium to cool the molten salt batteries easily.

摘要： A separator (3) of a molten salt battery is impregnated with a molten salt that serves as the electrolyte. The molten salt contains, as cations, at least one kind of ions selected from among quaternary ammonium ions, imidazolium ions, imidazolinium ions, pyridinium ions, pyrrolidinium ions, piperidinium ions, morpholinium ions, phosphonium ions, piperazinium ions and sulfonium ions in addition to sodium ions. These cations do not have adverse effects on a positive electrode (1). In addition, the melting point of the molten salt, which contains sodium ions and the above-mentioned cations, is significantly lower than the operating temperature of sodium-sulfur batteries, said operating temperature being 280-360 DEG C. Consequently, the molten salt battery is capable of operating at lower temperatures than sodium-sulfur batteries.
