<P>PROBLEM TO BE SOLVED: To provide a molten salt battery of which the cycle life is improved by using an electrolyte in which corrosion of aluminum is hard to be generated. <P>SOLUTION: In the molten salt battery, the total concentration of an iron ion and nickel ion contained in the electrolyte made of molten salt as impurity is made to be 0.1 wt.% or less, desirably 0.01 wt.% or less. The corrosion of a current collector of an electrode formed of aluminum is suppressed and the cycle life of the molten salt battery is improved by the low total concentration of the iron ion and nickel ion contained in the electrolyte. <P>COPYRIGHT: (C)2012,JPO&INPIT |
