Ultra-long-term cycling stability of an integrated carbon–sulfur membrane with dual shuttle-inhibiting layers of graphene “nets” and a porous carbon skin†
Abstract
An integrated carbon–sulfur (CSG/PC) membrane with dual shuttle-inhibiting layers was prepared by inserting graphene “nets” and a porous carbon (PC) skin, and the membrane achieved an extraordinary cycling stability up to 1000 cycles with an average Coulombic efficiency of ∼100%.
