| چکیده مقاله: |
| Energy storage systems are considered as one of the successful examples in reducing environmental pollution, but their performance to achieve high performance materials is still a major challenge. Today, various substrates with cathodic and anodic materials in energy storage systems especially batteries are composite including carbon substrates (including graphene oxide and carbon nanotubes, etc.), polymer substrates, and finally Metal–organic frameworks (MOFs). Meanwhile, energy researchers have considered carbon substrates in the last few decades due to their reasonable price, easy synthesis methods and good performance. Graphene oxide is a two-dimensional material with a hexagonal and crystalline structure that is made of a single layer with oxygen on its plates. Oxygen groups disrupt the basic structure of graphene, thus affecting and reducing its basic properties such as conductivity (electrical-thermal). defects and lattice strains obtained to find the optimal amount of nickel contamination. The electrochemical performance of the synthesized cathode materials has also been investigated by electrochemical impedance, cyclic voltammetry, and galvanostatic charge charging and discharging.N-rGO ,rGO capacity of 219.52 and 120.10 mAhg-1, respectively, at a current density of 500 mAg-1 . The results show that the sample with graphene oxide substrate doped with nitrogen shows electrochemical performance and higher capacity and maintenance capacity which can be used as a cathode in magnesium batteries. |
