Abstract: To improve the specific capacity and cycle stability of lithium-sulfur (Li-S) battery, a TiC/Celgard coating separator was developed and its performance in Li-S battery was investigated. The electrochemical test results confirmed that the TiC coating layer could significantly increase the capacity and cycle stability. At a high rate of 2C, it still delivered the capacity of 650 mAh?g-1. At 0.5C, the specific capacity was maintained at 841.3 mAh?g-1 after 100 cycles.

Key words: Li-S battery, TiC, Coating separator
