B/N co-doped carbon nanosphere frameworks as high-performance electrodes for supercapacitors

Abstract

A novel B/N co-doped carbon nanospheres framework is synthesized by a facile, economic, environmental and scalable method. The as-obtained materials display extra-high capacitive performance and exceptional long cycle stability with the merits of high energy and power density. We believe that this material will be applicable in the application of integrated energy storage devices.
