Lithium–Sulfur Batteries: Self‐Supported and Flexible Sulfur Cathode Enabled via Synergistic Confinement for High‐Energy‐Density Lithium–Sulfur Batteries (Adv. Mater. 33/2019)

Abstract

In article number 1902228, Jun Liu, Yan Yu, Min Zhu, and co-workers describe the design and use of a flexible sulfur cathode integrating sulfur, flexible carbon cloth, and N-doped carbon nanoarrays with embedded CoP for lithium–sulfur batteries. The structure and the synergistic confinement for soluble lithium polysulfides lead to an outstanding long-term cycling performance and an ultralow decay of 0.016% per cycle over 600 cycles at 2C.
