摘要： Provided is a method for producing a negative electrode for an electric storage device, the method comprising the steps of: preparing a negative electrode composition comprising a negative electrode active material that reversibly carries a sodium ion, metal sodium, and a liquid dispersion medium for dispersing them; allowing a negative electrode current collector to hold the negative electrode composition; evaporating at least part of the liquid dispersion medium from the negative electrode composition held by the negative electrode current collector, thereby giving a negative electrode precursor comprising the negative electrode active material, the metal sodium, and the negative electrode current collector; and bringing the negative electrode precursor into contact with an electrolyte having sodium ion conductivity, thereby doping the negative electrode active material with sodium eluted from the metal sodium.

摘要： A separator for use in a molten salt battery has the problem that due to usage specific to the molten salt battery, the separator is placed under mechanical, thermal and chemical stress, so that cracking or rupture easily occurs, leading to a degradation in battery performance such as an internal short-circuit. The molten salt battery of the present invention includes a separator containing a metal oxide, particularly aluminum oxide and/or zirconium oxide in an amount of 75% or more. The separator improves mechanical, thermal and chemical resistance, and thus an internal short-circuit ascribable to the separator is hard to occur, so that the molten salt battery can be stably operated for a long period of time. The separator has high heat stability, so that the safety of the molten salt battery can be improved.

Both faces of the negative electrodes are covered with the separators which are formed to bend along a lower end part of the respective positive electrodes. The separators respectively have a V-shaped or U-shaped cross section, a bent part is formed to have a valley-like (groove-like) shape, and the respective bent parts are disposed along a lower side of the positive electrodes. The positive electrodes having both faces covered with the respective separators as described above and the negative electrodes are laminated alternately. The dimension of the separators after being bent is made larger than that of the positive electrodes and the negative electrodes by 1 to 10%.

摘要： Provided is a molten salt battery whose cycle life is improved by using an electrolyte that is unlikely to cause corrosion of aluminum. In the molten salt battery of the present invention, the total concentration of iron ions and nickel ions contained as impurities in the electrolyte composed of a molten salt is set to be 0.1% by weight or less, preferably 0.01% by weight or less. Because of the low total concentration of iron ions and nickel ions contained in the electrolyte, corrosion of the electrode current collector composed of aluminum is inhibited, and the cycle life of the molten salt battery is improved.
