摘要： An element recovery method and an element recovery apparatus are provided by which an element containing a high-purity rare earth element can be recovered at low cost. The element recovery method includes the steps of: preparing molten salt containing a rare earth element; and controlling electric potentials in a pair of electrode members at prescribed values while keeping the pair of electrode members in contact with the molten salt, thereby depositing the rare earth element existing in the molten salt on one of the pair of electrode members. In this way, as compared with the conventional wet separation method, an element such as a rare earth element that is to be recovered can be directly recovered from the molten salt in which the element is dissolved, so that the steps of the recovery method can be simplified and reduced in cost.

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： 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： 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： The present invention relates to a metal catalyst containing fine metal particles, characterized in that the fine metal particles have a particle diameter of 3 nm or less and also have a proportion of metallic bond state of 40% or more, which is ascribed by subjecting to waveform separation of a binding energy peak peculiar to the metal as measured by using an X-ray photoelectron spectrometer. The fine metal particles are preferably fine platinum particles. The fine metal particles are preferably supported on the surface of carrier particles by reducing ions of metal to be deposited through the action of a reducing agent in a reaction system of a liquid phase containing the carrier particles dispersed therein, thereby to deposit the metal on the surface of carrier particles in the form of fine particles. The proportion of metallic bond state of the fine metal particles is adjusted within the above range by reducing after deposition thereby to decrease the oxidation state.
