AbstractLi2S holds a promising role as a high-capacity Li-containing cathode, circumventing use of metallic lithium in constructing next-generation batteries to replace current Li-ion batteries. However, progress of Li2S cathode has been plagued by its intrinsic drawbacks, including high activation potentials, poor rate performance, and rapid capacity fading during long cycling. Herein, a series of Li2S/transition metal (TM) nanocomposites are synthesized via a lithiothermic reduction reaction, and it is realized that the presence of TMs in Li2S matrix can transform electrochemical behaviors of Li2S. On the one hand, the incorporation of W, Mo, or Ti greatly increases electronic and ionic conductivity of Li2S composites and inhibits the polysulfide dissolution via the TM-S bond, effectively addressing the drawbacks of Li2S cathodes. In particular, Li2S/W and Li2S/Mo exhibit the highest ionic conductivity of solid-phase Li-ion conductors ever-reported: 5.44 x 10(-2)and 3.62 x 10(-2)S m(-1), respectively. On the other hand, integrating Co, Mn, and Zn turns Li2S into a prelithiation agent, forming metal sulfides rather than S(8)after the full charge. These interesting findings may shed light on the design of Li2S-based cathode materials.
