“…The key to solving this problem lies in the rational selection of electrode materials, which determine the electrochemical performance of SCs. Among various electrode materials, carbon materials including carbon nanotubes (Sharma et al, 2015), carbon nanosphere (Cui and Zhu, 2014), active carbon (Kołodynska et al, 2016), and graphene (Wang et al, 2017;Yang et al, 2017) have been widely utilized for high-performance SCs constructions because of their impressive merits such as large surface area, prominent electrical conductivity, admirable long-term cycling stability, good mechanical properties, low production cost, and environmental friendliness (Gnanasekaran et al, 2017;Zhao et al, 2017;Guo et al, 2018). Among them, graphene has been considered as the most attractive candidate due to its high theoretical surface area (2,630 m 2 g −1 ), impressive electrical conductivity and unique structure (Cao et al, 2011;Shen et al, 2017;Yu et al, 2017).…”

Graphene for energy storage devices suffers from the preparation method and deficient quality, hindering their further widespread application. Here, we report a facile and cost-effective approach to derive three-dimensional porous graphene (3DPG) from biocompatible chitosan for massive production. Taking advantage of the large surface area, excellent electrical conductivity and high electrochemical activity of the 3DPG, an advanced symmetric supercapacitor (3DPG//3DPG SCs) is achieved by coupling two 3DPG electrodes in commercial DLC301 organic electrolyte. The device delivers a remarkable capacitance of 168.9 F g-1 at the scan rate of 10 mV s-1 and displays a superior rate capability, witnessing 81.5% capacitance retention from 10 to 100 mV s-1. Furthermore, the 3DPG//3DPG SCs exhibits prominent cyclic durability, as evidenced by its 96% capacitance after 10,000 cycles. This work might shed light on the probable application of graphene at industrial level for efficient energy storage.
