Abstract: Provided is a molten salt battery device and a temperature control method for a molten salt battery, which enable the molten salt battery temperature to be controlled at a uniform temperature and which also enable easy cooling. The molten salt battery device arranges a plurality of molten salt batteries (1) within a container (2) such that space is provided around the molten salt batteries (1), fills the space around the molten salt batteries (1) with a heat medium (3), and makes the heat medium (3) flow while controlling the temperature of the heat medium (3) with a temperature control unit (52) by the use of an electric heater (51). The molten salt battery device controls the temperature of the molten salt battery (1) by the heat exchange between the flowing heat medium (3) and the molten salt battery (1). The internal temperature of the molten salt battery (1) is controlled to a uniform temperature by the heat exchange with the heat medium (3) that surrounds the molten salt battery (1). The molten salt battery device can also easily cool the molten salt battery (1) by reducing the temperature of the heat medium (3).

Abstract: 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°C. Consequently, the molten salt battery is capable of operating at lower temperatures than sodium-sulfur batteries.

Abstract: There is provided a magnesium alloy member having mechanical properties and corrosion resistance and a method of manufacturing the magnesium alloy member. A magnesium alloy member has a base material made of a magnesium alloy, and an anticorrosive film formed on the base material. The base material is a rolled magnesium alloy including 5 to 11% by mass of Al. By using a base material including a large amount of Al, a magnesium alloy member having excellent mechanical properties and high corrosion resistance can be produced. In addition, by using a rolled material, the number of surface defects at the time of casting is small, and the frequency of compensation processes such as undercoating and puttying can be reduced:

Abstract: Disclosed is a capacitor (100) equipped with a positive electrode (10), a negative electrode (20), and a solid electrolyte layer (30) disposed between these electrode layers (10) and (20). At least one of the electrode layers (10) and (20) comprises porous Al (11) and an electrode material (12 or 13) which is held by the porous Al (11) and which polarizes the electrolyte. The porous Al (11) has a surface oxygen amount of 3.1 mass% or less. That the porous Al (11) has a surface oxygen amount of 3.1 mass% or less is equal to that substantially no oxide film having high resistance has been formed on the surface of the porous Al (11). Due to this porous Al (11), the electrode layer (10 or 20) can have an increased current collection area and, hence, the capacitor (100) can have an improved capacity.

Specifically disclosed is a molten salt battery (1) which comprises a positive electrode (2) comprising an Al-made current collector (21) and an active material layer (22) formed on the current collector (21), a separator (3) comprising a glass cloth impregnated with a molten salt that serves as an electrolyte, and a negative electrode (4) comprising a Zn coating film (42) and an active material layer (43) both formed on an Al-made current collector (41), wherein the positive electrode (2), the separator (3) and the negative electrode (4) are contained in an almost rectangular parallelepiped Al-made case (5). The active material (43) can store and release Na ions contained in the molten salt.
