LITHIUM/DISSOLVED POLYSULFIDE RECHARGEABLE LITHIUM- SULFUR BATTERIES AND METHODS OF MAKING THE SAME

摘要

In one embodiment, the present disclosure relates to a rechargeable Li-S battery including a cathode including a firbrous carbon material, a catholyte including a polysulfide, and an anode. In another embodiment, the present disclosure relates to a charged or partially charged rechargeable Li-S battery including a cathode including a fibrous carbon material and amorphous microparticles of elemental sulfur, a catholyte including high-order polysulfides having a general formula of Li₂S_n, wherein n is at least eight, and an anode. In another embodiment, the present disclosure relates to a discharged or partially discharged rechargeable Li-S battery including a cathode including a fibrous carbon material and amorphous microparticles of Li₂S, a catholyte including a negligible amount of polysulfides, and an anode.
