The suitability of some different kinds of liquid electrolytes with a 1M solution of LiCF3SO3 was evaluated for discharging capacity and cycle performance of Li/S cells at room temperature. The liquid electrolyte component was found to have a profound influence on the discharging capacity and cycle property. The lithium–sulfur battery based on the alcohol-ether binary electrolyte shows two discernible voltage plateaus at around 2.4 and 2.1 V, which correspond to the formation of soluble polysulfides and of solid reduction products, respectively. However, the liquid electrolyte based on carbonate electrolyte shows a bad compatibility with sulfur cathode. The lithium sulfur battery can not deliver acceptable discharging capacity and cycle performances.
