title: Fabrication of mesoporous Li2S-C nanofibers for high performance Li/Li2S cell cathodes.
abstract: A Li2S electrode is a very promising cathode for Li-ion batteries. However, the high voltage needed to activate Li/Li2S cells represents a challenging problem. Here, we report for the first time a mesoporous Li2S-C nanofiber composite with 72 wt% Li2S. The assembled Li/Li2S cells showed a low and stable voltage plateau of 2.51 V for the first charge and can deliver a high initial discharge capacity of ∼800 mA h g(-1).
