All-solid-state lithium-sulfur batteries are promising from the perspective of high safety, low cost, and high capability. Herein, composites of sulfur and microporous carbon (MSP20, MSC30) are prepared by a melt diffusion process, and their performance as electrode materials are compared with that of composites based on nanocarbons. In addition to the type of carbon, the degree of mixing with solid electrolytes is an important factor in the formation of ionic/electronic conduction pathways. The all-solid-state cell using S-MSC30-Li3PS4 shows a high initial discharge capacity of 1488 mAh per gram of sulfur at 25 degrees C at a current density of 1.3 mA cm(-2) and operates reversibly at a high current density of 12.7 mA cm(-2) (3C) at 100 degrees C. The amorphization of sulfur is effective for obtaining high capacity and sulfur impregnated into the meso- and micropores of carbon is more active than sulfur that forms nanocomposites with nanocarbon.
