One‐stepsynthesis of nitrogen‐doped graphene powders and application of them ashigh‐performancesymmetrical coin cell supercapacitors in different aqueous electrolyte

“…Since N1-GP and N2-GP graphene powders were synthesized in a wider potential range, the oxygenated functional groups doped to the surface by oxidation were removed from the structure with reduction, while the nitrogen element was doped to the structure as pyridinic and pyrolytic N (Figures S6 and S7). 33,51 Since it was synthesized in the widest potential range, the graphene powder N1-GP had the least amount of oxygenated groups upon the reduction process. Consequently, graphene powders synthesized in narrow potential ranges had higher supercapacitor performances.…”

“…Carbon‐based materials are widely used thanks to their advantages such as adjustable electronic properties, replaceable chemical structure, superior mechanical properties and reusability 31 . The use of graphene materials in supercapacitors improves the properties of the supercapacitor as well as its performance 32,33 . During high cycle charge and discharge, the capacity of the system improves thanks to its stable structure.…”

“…31 The use of graphene materials in supercapacitors improves the properties of the supercapacitor as well as its performance. 32,33 During high cycle charge and discharge, the capacity of the system improves thanks to its stable structure. They can be used without the need for an extra cooling system with the help of their thermal resistance.…”

Production of chlorine-containing functional group doped graphene powders using Yucel's method as anode materials for Li-ion batteries

“…In this context, the research on systems that store energy in chemical forms, such as rechargeable batteries (lead-acid batteries, redox ow batteries, lithium (Li)-ion batteries) and supercapacitors, has continues at an incredible pace. [4][5][6][7][8][9][10][11][12] Since lithium is the lightest metal, it is an extremely suitable candidate for use in rechargeable battery applications. This metal has been extensively researched for nearly half a century, and different Li-ion batteries with positive or negative electrodes consisting of lithium or lithium-containing compounds have been synthesized.…”
