Effect of Organic Additives in Electrolytes for Rechargeable Lithium/Sulfur Battery

The effect of mixed electrolytes and organic additives on the electrochemical performance of rechargeable lithium/sulfur battery is investigated. The mixture of organic electrolytes, DME, DIG, TEGDME, and DIOX, was prepared to have appropriate composition, and to the electrolyte were added various organic additives, such as toluene, γ-butyrolactone, and MA. They showed an improved cyclic efficiency of lithium/sulfur battery and made utilization of active material, sulfur, more effective.
