“…To evaluate the specific surface area of the 3DPG sample, nitrogen adsorption-desorption measurement was carried out in Figure 2B. More encouragingly, the Brunauer-Emmett-Teller (BET) specific surface area of the 3DPG sample reaches up to 330.0 m 2 g −1 , which exceeds that of most graphene (Yang et al, 2011(Yang et al, , 2014(Yang et al, , 2015. Additionally, to gain insight into the chemical composition and valence state of the 3DPG, the sample was investigated by Raman spectroscopy and X-ray photoelectron spectroscopy (XPS).…”

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.

Membrane capacitive deionization (MCDI) featuring both high electrosorption capacity and high energy effi ciency holds promise for desalination. However, the large-scale applications of MCDI are limited greatly by the high cost of commercial ion-exchange membranes and the interfacial resistance. Here, a new strategy for high-performance MCDI is established using sulfonated graphene (SG) as cation-selective coating. A continuous ultrathin SG coating via self-assembly is formed and attached tightly onto the surface of electrospun carbon nanofi bers (CNFs) by a simple yet effective dip-coating technique, yielding SG-CNF composites with a hydrophilic surface, high electrochemical specifi c capacitance, and greatly reduced interfacial charge transfer rate. These result in signifi cantly enhanced capacitive deionization performance in terms of both electrosorption capacity and charge effi ciency. The SG coating shows excellent cation selectivity for an asymmetric cell with SG-CNFs as a cathode. The new approach may pave a way to novel micro-MCDI, i.e. novel applications of functional graphene-based materials for highperformance, energy-effi cient, and cost-effective desalination.Adv. Mater.
