Journal ArticleDOI
Facile Route to an Efficient NiO Supercapacitor with a Three-Dimensional Nanonetwork Morphology
TL;DR: This study indicates that forming a 3D nanonetwork is a straightforward means of improving the electrochemical properties of a supercapacitor.
Journal ArticleDOI
Chemical Vapor Deposition of Mesoporous Graphene Nanoballs for Supercapacitor
TL;DR: A mass-producible mesoporous graphene nanoball fabricated via a precursor-assisted chemical vapor deposition (CVD) technique for supercapacitor application proves the strong potential for use in energy-related areas.
Journal ArticleDOI
Recent Advances in Lithium Sulfide Cathode Materials and Their Use in Lithium Sulfur Batteries
TL;DR: In this paper, an overview of these efforts, as well as of the various full-cell systems that have been subsequently developed based on Li2S cathodes in combination with different anode materials such as silicon nanowires, silicon thin films, and tin composites is provided.
Journal ArticleDOI
Fully flexible, lightweight, high performance all-solid-state supercapacitor based on 3-Dimensional-graphene/graphite-paper
TL;DR: In this article, a paper-based symmetric supercapacitor was fabricated on a flexible graphite-paper substrate and exhibited a maximum capacitance of 260 F ǫg −1 (15.6 mFǫ ) in a three electrode system, 80 F g − 1 (11.1 mF ) in full cell, high capacitance retention and a high energy density.
