F. Li, H.‐M. Cheng, and co‐workers develop a flexible Li–S battery based on an integrated structure of sulfur and graphene on a separator with excellent flexibility, mechanical properties, and high energy density. The internal graphene current collector offers a continuous conductive pathway, a modified interface with sulfur, and a good barrier to, and an effective reservoir for, the dissolved polysulfides, consequently improving the capacity and cyclic life of the Li–S battery, as shown on page 641.
