Abstract

Abstract : Supercapacitors Translating the materials metrics of graphene into supercapacitor performance is critical but engineering capacitive energy storage is challenging. In article number 2203761, Jinyou Shao and co‐workers introduce a bubble‐induced method for fabricating graphene microspheres with high ion conductivity and efficient utilization of surface area, enabling stack supercapacitors to deliver a high energy density of 83.4 Wh L −1, close to that of lead‐acid batteries.
