摘要

The development of high-performance supercapacitors requires efforts in materials design and nanotechnology to provide more efficient electrodes with higher electrochemical window, capacitance, energy and power density. In terms of candidates for electrodes, the high surface area of graphene (2630 m2g-1) makes this carbon derivative a widely explored building block for supercapacitor electrodes. Herein, it is presented a review about the state-of-art in surface modification of graphene derivatives with the aim of avoiding restacking processes in nanosheets. It allows that Faradaic and non-Faradaic mechanisms can be synergically explored to reach not only superior results in power density but in energy density, a typical drawback in supercapacitors (by comparison with conventional batteries), introducing graphene-based supercapacitors as promising candidates for energy storage devices.
