Title:
METHOD FOR OPERATING MOLTEN SALT BATTERY
Document Type and Number:
WIPO Patent Application WO/2013/058079
Kind Code:
A1
Abstract:
Disclosed is a method for operating a molten salt battery that comprises: a molten salt as an electrolytic solution; a sodium compound (NaCrO2) as a positive electrode; and tin (Sn) as a negative electrode. The operation temperature range of this molten salt battery is normally from 57°C to 190°C. However, by operating this molten salt battery by setting the inner temperature thereof (the temperature of the electrodes and the molten salt) from 98°C to 190°C, the sodium is brought into the liquid phase and penetrates into the Sn-Na alloy that has been reduced to fine particles on the negative electrode. Thus, the detachment of the Sn-Na alloy is inhibited.
