Rapidly annealed nanoporous graphene materials for electrochemical energy storage

Author affiliations

Abstract

The urgent need for efficient energy storage devices greatly stimulates the development of high power, highly efficient, environmentally friendly, and low-cost energy storage devices. Supercapacitors, unlike batteries, store energy by ion adsorptions on high surface area electrodes. The physical ion migration provides a high charging/discharging rate, power density, and reversibility. In this work, we synthesize graphene materials by a rapid thermal annealing process and examine the material properties. With the synthesized graphene as electrodes, the outstanding electrochemical performance of these supercapacitors is demonstrated. This provides a new method for developing supercapacitors with high charge/energy storage capability at low cost.
