Title: Interaction of TiS 2 and Sulfur in Li-S Battery System

With the ability to adsorb polysulfide, electronically conductive and electrochemically active TiS 2 is an effective multifunctional cathode additive to improve Li-S battery cycling performance. Furthermore, by using X-ray Photoelectron Spectroscopy (XPS), direct evidence is obtained to demonstrate the strong interaction between Li-polysulfide and TiS 2. The observation of Li signature on Li 2S 8 treated TiS 2 proves that the TiS 2 possesses the ability to adsorb Li-polysulfides species on its surface. An electron density transfer from Ti to Li and S is identified based on the positions of the peaks in the XPS spectrum before and after the interaction, which is consistent with the theoretically predicted polysulfide-TiS 2 interaction models in the literature. TiS 2 sample with 2.5x higher BET surface area is obtained by milling the raw TiS 2 particles and used as cathode additive in the sulfur electrode. Furthermore, in the presence of TiS 2 additive, long cycle life and improved sulfur utilization of Li-S cells under high rate discharge are demonstrated. In addition, we find that a uniform TiS 2 distribution in the sulfur-TiS 2 hybrid electrode is vital in determining its effectiveness in enhancing the performance of sulfur electrodes. Thus, by processing method andmore » condition should be very important considerations in future development of sulfur electrodes with TiS 2 additive.« less
