Li2S/S Driving method of Li2S/S symmetric cell

摘要

The present invention provides a method for operating a Li_2S/S symmetric cell, which increases a charging/discharge speed of the Li_2S/S symmetric cell more than a self-discharge speed due to elution of polysulfide. According to the present invention, the method can minimize effect by the elution and movement of the polysulfide; can be operated without using an electrolyte, membrane, and the like for reducing the elution and movement of the polysulfide; can easily figure out characteristics of a material which cannot be confirmed by effect of a lithium electrode in a lithium-sulfide cell; and can be operated in the same system (using the same material) as a system of the lithium-sulfide cell to increase reliability in an analysis method.
