Hongjun Park, Raj Kumar Bera, Ryong Ryoo
Abstract
Battery-Supercapacitor Hybrids In article number 2100076, Hongjun Park, Raj Kumar Bera, and Ryong Ryoo fabricate a high-performance battery-supercapacitor hybrid electrode by embedding iodine in microporous 3D graphene-like carbon. The electrically conductive framework of 3D graphene-like carbon serves as a path for fast charge transfer. The device exhibits high energy and power densities, which is highly desirable in high-power electronics and electric vehicles.
