摘要：

Here we proposed a novel approach to greatly enhance the electrochemical performance of Li–S batteries by designing a composite electrode material composed of a core-shell structure of S@Pt composite (sulfur content, 85%) grown on the S surface. The platinum (Pt) nanosheets provide physical barrier and strong chemical binding to anchor LiPSs and improve the electronic conductivity of S. Significantly, by introducing carbon nanofibers (CNFs) as the interlayer, we achieved outstanding Li–S battery with a high initial discharge capacity of 1040 ...
