Abstract

Abstract: In order to study the effects of electrolytes on the electrochemical properties of sulfur cathode for rechargeable lithium sulfur batteries, viscosities, ionic conductivities and sulfur solubilities of binary and multiple solvent 1 mol/L LiCF₃SO₃ electrolytes based on 1,3-dioxolane(DOL) were measured. The results from cyclic voltammograms and various discharge profiles indicated that the electrolyte with the lower viscosity and the higher donor number could favor to improve the redox reaction activity and reversibility of the sulfur cathode, and correspondingly to improve the low discharge voltage plateau and the discharge rate. Furthermore, an electrolyte with the lower viscosity preferred to improve the surface layer microstructure of the sulfur electrode, to increase the ionic diffusion rate of electroactive species and to decrease the charge transfer resistance. At the charge/discharge current density of 0.1/0.2 mA/cm², sulfur cathode achieved an initial discharge specific capacity of 792 mA·h/g and the specific capacity of 412 mA·h/g of the 29th discharge.
