Supercapacitors: Ultrathin and Porous Ni 3 S 2 /CoNi 2 S 4 3D‐Network Structure for Superhigh Energy Density Asymmetric Supercapacitors (Adv. Energy Mater. 21/2017)

Abstract

Ultrathin, porous and free-standing 3D-network structures are successfully designed and synthesized by a simple sulfidation process on the nanosheets-assembled 3D-networked precursor. The positive electrode obtained by such 3D-network structures for asymmetric supercapacitors possesses high energy density and excellent stability. This work reported by Huiqiao Li, Xijin Xu, Tianyou Zhai, and co-workers in article number 1700983 will provide new ideas for the development of electronic devices.
