    摘要: Provided are a molten salt battery device capable of controlling the temperature of its molten salt batteries evenly and being further cooled easily; and a method for controlling the temperature of a molten salt battery.
    In the molten salt battery device, molten salt batteries 1 are arranged in a container 2 to cause a space to be present around the molten salt batteries 1, and a heating medium 3 is filled into the space around the molten salt batteries 1. While an electrothermal heater 51 is used to control the temperature of the heating medium 3 through a temperature controlling section 52, the heating medium 3 is caused to flow. Between the flowing heating medium 3 and the molten salt batteries 1, heat is exchanged, whereby the molten salt battery device controls the temperature of the molten salt batteries 1. Since the molten salt batteries 1 attain the heat exchange with the heating medium 3, 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 3 to cool the molten salt batteries 1 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.

    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.
