  • FIRST-PRINCIPLES STUDY OF GA-N CO-DOPED GRAPHENE NANOSTRUCTURES 
    Akhmetsadyk, Dinara; Guseinov, Nazim; Ilyin, Arkady (National Laboratory Astana, 2022-08)
    Graphene's physical properties have made it interesting and used in a range of fields of science and technology, such as medicine, nanoelectronics, sensors, and desalination. A simple method for manufacturing graphene with ...
  • Improved Performance of LiFe0.25Mn0.75PO4 by using Graphene and Fluorine- Doped Carbon Coating 
    Liu, Jian; Sun, Deye; Zhang, Zengqi; Zhang, Li; Jin, Yongcheng (The 6th International Conference on Nanomaterials and Advanced Energy Storage Systems. Institute of Batteries LLP, Nazarbayev University, and PI “National Laboratory Astana”., 2018-08-08)
    Lithium transition metal phosphatesusually need modification of morphology and electron conductivity for improving the electrochemical performance [1,2]. In this work, the electron conductivity of LiFe0.25Mn0.75PO4 is ...
  • MICROWAVE-ASSISTED SYNTHESIS OF LISICON STRUCTURED LI3V2(PO4)3/ GRAPHENE COMPOSITE 
    Mukushev, Ilyas; Nurpeissova, Arailym; Kalimuldina, Gulnur; Bakenov, Zhumabay (National Laboratory Astana, 2022-08)
    One of the main challenges in cathodes at low temperatures (LT) is associated with low electronic and ionic conductivity. Graphene can be used to increase electronic conductivity, but most of the experimental methods for ...
  • Multiscale simulation of ion beam impacts on a graphene surface 
    Dybyspayeva, K. B.; Zhuldassov, A.; Ainabayev, A.; Vyatkin, A. F.; Alekseev, K.; Insepov, Z. (IOP Publishing, 2016-09)
    Multiscale study of single and multilayer graphene irradiation is presented in this paper. Ab-initio density-functional theory (DFT) was used to study point defects, and a large scale parallel molecular-dynamics (MD) ...
  • A novel CuS/graphene-coated separator for suppressing the shuttle effect of Lithium/sulfur batteries 
    Zhang, Yongguang; Sun, Liancheng; Zhao, Yan (The 6th International Conference on Nanomaterials and Advanced Energy Storage Systems. Institute of Batteries LLP, Nazarbayev University, and PI “National Laboratory Astana”., 2018-08-08)
    We demonstrate a facile synthesis process to fabricate and deposit flower-like CuS/graphene nanocomposite on a multi-functional separator for efficient immobilization of polysulfides of lithium/sulfur (Li/S) batteries.
