      abstract     = {Li2S has made the concept of Li–S batteries much more
                      promising due to the relatively high storage capacity, the
                      possibility of using Li-free anodes and the increase of
                      microstructural stability. However, similar to S, Li2S also
                      suffers from an insulating nature and polysulfide
                      dissolution problem. The results presented here show a
                      facile and cost-effective approach by using a plasma
                      sparking and chemical sulfurization process to synthesize
                      core–shell Li2S@C nanocomposites. The nanocomposites show
                      a significantly reduced particle size and well-developed
                      core–shell architecture, effectively shortening the Li-ion
                      diffusion distance, enhancing the electronic conductivity
                      and suppressing the dissolution losses of polysulfides. As a
                      result, a much improved rate and cycling performance has
                      been achieved. The method presented in this study offers
                      good opportunities for scaling up the production of high
                      performance cathode materials in a simple and low-cost way
                      to be applied in future generation Li–S batteries.},
