Abstract: 

The effect of sulfur content in positive electrodes (the surface capacity of sulfur electrodes) on the characteristics (such as the depth of sulfur electrochemical reduction, changes in capacitance and Coulomb efficiency during cycle life) of lithium-sulfur cells with electrolytes based on sulfolane was studied. It was shown that the reason for the capacitance decrease of the lithium-sulfur cells at the early stage of its cycle life is the displacement of sulfur of the porous positive electrode from the rear regions into the front ones. It was established that in order to achieve the maximum possible specific energy of the lithium-sulfur batteries with the electrolytes based on sulfolane, the surface capacitance of the positive electrodes should be in the range of 2-3 mA⋅h/cm2.
