Performance of Blended TiS2/Sulfur/Carbon Cathodes in Lithium-Sulfur Cells

The preparation and electrochemical testing of blended TiS2/sulfur/carbon cathodes in lithium-sulfur cells is described in this paper. TiS2, sulfur and carbon were combined in various ratios and the resulting electrodes were investigated regarding their reversible capacity and degradation behavior in lithium-sulfur cells. The capacity of corresponding cathodes depends on the amount of TiS2 used. The maximum capacity was somewhat lower (compared to sulfur/carbon cathodes) when TiS2 was added, but it was observed that TiS2 improved the pulse power capability of corresponding lithium-sulfur cells.
