Abstract

cell configuration lithium–sulfur batteries microstructures polysulfide trapping pore size analysis
In article number 1500738, Arumugam Manthiram and co‐workers report the design of a custom separator with an activated carbon nanofiber (ACNF) filter coating on a polypropylene membrane. The entire configuration is composed of the ACNF‐filter coating arranged adjacent to the sulfur cathode so that it can suppress polysulfide diffusion. A comparative analysis of four differently optimized ACNF‐filter‐coated separators provides insight into the polysulfide‐trapping mechanism and demonstrates an overall boost in the cell performance.
