Supercapacitors: Battery‐like Supercapacitors from Vertically Aligned Carbon Nanofiber Coated Diamond: Design and Demonstrator (Adv. Energy Mater. 12/2018)

In article number 1702947, Nianjun Yang, Xin Jiang and co-workers construct high performance supercapacitors by use of integrated boron-doped sp3-diamond with vertically aligned sp2-carbon nanofibers in inert and redox-active electrolytes. Such battery-like supercapacitors exhibit large and stable capacitances as well as both high power and energy densities. As confirmed by a stand-alone demonstrator, these supercapacitors are promising for powering multifunctional electronics, hybrid electric vehicles, and industrial equipment in the future.
