Document Type and Number:
WIPO Patent Application WO/2014/171196
Kind Code:
A1
Abstract:
Provided are a molten salt electrolyte having excellent charge/discharge cycle characteristics and a sodium molten salt battery using same. The molten salt electrolyte comprises: an ionic liquid in which the UV-visible absorption spectrum does not have an absorption peak that is attributed to impurities in the wavelength range of 200-500 nm; and a sodium salt. The sodium molten salt battery comprises a positive electrode that contains a positive electrode active material, a negative electrode that comprises a negative electrode active material, and the molten salt electrolyte. It is preferable that the ionic liquid be a salt of an organic onium cation and a bis(sulfonyl)imide anion.
