“…There are several methods for graphene preparation, such as chemical vapor deposition (Suk et al, 2011), epitaxial growth , mechanical exfoliation (Yi and Shen, 2015), chemical exfoliation (Liu and Wang, 2011), electrochemical exfoliation (Yang et al, 2015;Bakunin et al, 2019), and so on. It is worth noting that electrochemical exfoliation has been deemed a useful technique in producing high-quality graphene on a large scale owing to it being environmentally friendly, low cost, and requiring only simple operations (Low et al, 2013;Ejigu et al, 2019).…”

Doping heteroatom, an effective way to enhance the electrochemical performances of graphene, has received wide attention, especially related to nitrogen. Alternating voltage electrochemical exfoliation, as a low cost and green electrochemical approach, has been developed to construct in-situ N-doped graphene (N-Gh) material. The N-Gh presents a much higher capacity than that of pure graphene prepared via the same method, which might be attributed to the introduction of nitrogen, which has much more effects and a disordered structure. As-prepared N-Gh exhibits a low O/C ratio that is helpful in maintaining high electrical conductivity. And the effects and disorder structure are also conductive to reduce the overlaps of graphene layers. A symmetric supercapacitor assembled with N-Gh electrodes displays a satisfactory rate behavior and long cycling stability (92.3% retention after 5,000 cycles).
