Graphene-nanoscroll-based Integrated and self-standing electrode with a sandwich structure for lithium sulfur batteries†
Abstract
Alleviating the shuttling of polysulfides in a lithium sulfur battery is an important way of improving their electrochemical performance. Herein, sulfur was confined into a graphene nanoscroll (GNS), which was sandwiched by GNS/MnO2 hybrid nanowires to form an integrated electrode. Due to its unique structure and composition, the electrode exhibited a surperior ability to trap polysulfides.
