Vertically Oriented Graphene Nanosheets for Electrochemical Energy Storage

Abstract

Invited for this month's cover picture is the group of Professor Shaowei Chen from the University of California (USA). The picture shows an array of graphene nanosheets vertically grown onto a substrate that may be used as effective electrodes for electrochemical energy technologies (e.g. supercapacitors, lithium‐ion batteries, etc.). This is to take advantage of the large accessible surface area, rich edges, high electrical conductivity, open network channels, and agglomeration resistance, unique characteristics unseen with conventionally, randomly, or horizontally oriented graphene derivatives.

Application of Graphene in Lithium-Ion Batteries

“…High-quality foamed graphene and vertical graphene prepared by chemical vapor deposition (CVD) and plasma-enhanced chemical vapor deposition (PECVD) have emerged in the latest report, but the preparation process involves high temperatures and complex techniques. It is inferred that highend 3D graphene derivatives with few defects and high electronic conductivity are the development direction in the future [92,93].…”
