title: Enhancement of electrochemical properties by polysulfide trapping in a graphene-coated sulfur cathode on patterned current collector.
abstract: A sulfur cathode on a honeycomb-shape-patterned Al current collector was prepared and successfully sealed using triple-layered graphene. Graphene layers on the sulfur cathode well confined the dissolved polysulfide in the electrode, leading to significantly enhanced electrochemical properties including cycle retention and Coulombic efficiency.
