Enhancement of electrochemical properties by polysulfide trapping in a graphene-coated sulfur cathode on patterned current collector

Chem Commun (Camb). 2016 Feb 21;52(15):3203-6. doi: 10.1039/c5cc09694d.

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.
