High-performance Li/dissolved polysulfi de batteries with an advanced cathode structure and high sulfur content

Abstract

High-performance Li/dissolved polysulfide batteries with a high sulfur concentration of 60 wt% and a high sulfur loading of 5.5 mg cm-2 are demonstrated with a sandwich cathode containing a pristine carbon nanofiber current collector filled with polysulfides and a hydrophilic composite upper current collector for high sulfur utilization.
