Performance of Blended TiS_2/Sulfur/Carbon Cathodes in Lithium-Sulfur Cells

摘要

The preparation and electrochemical testing of blended TiS_2/sulfur/carbon cathodes in lithium-sulfur cells is described in this paper. TiS_2, 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 TiS_2 used. The maximum capacity was somewhat lower (compared to sulfur/carbon cathodes) when TiS_2 was added, but it was observed that TiS_2 improved the pulse power capability of corresponding lithium-sulfur cells.
