dc.description.abstract | Li2S is coated with carbon to improve the electrical conductivity of the composite cathode in all-solid-state lithium-sulfur batteries. Carbon is applied by thermal evaporation from a polyacrylonitrile (PAN) source at 600 degrees C for 5 h. It is shown that the carbon coating is impurity free, and the crystallinity of Li2S is well maintained. The electronic conductivity of Li2S is dramatically improved from 9.21 x 10(-9) S cm(-1) to 2.39 x 10(-2) S cm(-1) upon carbon coating. An all-solid-state battery prepared with the carbon-coated Li2S shows a high initial capacity of 585 mAh g(-1) (g of Li2S) that increases up to 730 mAh g(-1) (g of carbon-coated Li2S) by the 10th cycle. This high capacity is stable throughout the 25 cycles tested, with an excellent coulombic efficiency of 99%. Carbon-coated Li2S is advantageous for all-solid-state batteries due to the increased electrical conductivity, while allowing a reduction of the total carbon content present in the composite cathode. | en_US |
