  • DESIGN AND ENGINEERING OF ADVANCED SI-BASED THIN FILM ANODE MATERIALS FOR LI-ION BATTERIES 
    Mukanova, Aliya (Nazarbayev University, School of Engineering and Digital Science, 2019-06-17)
    Lithium-ion batteries (LIBs) are a versatile way of energy conversion and storage. Thin film batteries are the next generation of Li-ion battery technology with the thickness of tens μm and aimed to power a diverse range ...
  • The Electrochemical Performances of n-Type Extended Lattice Spaced Si Negative Electrodes for Lithium-Ion Batteries 
    Lee, Moonsang; Yoon, Dockyoung; Lee, Uk Jae; Umirov, Nurzhan; Mukanova, Aliya; Bakenov, Zhumabay; Kim, Sung-Soo (Frontiers Media, 2019-07)
    The electrochemical performances of lithium-ion batteries with different lattice-spacing Si negative electrodes were investigated. To achieve a homogeneous distribution of impurities in the Si anodes, single crystalline ...
  • Novel Li4Ti5O12/Si/c-PAN composite anode for Lithium-ion batteries 
    Nyssanbayev, Anuar; Sanbayeva, Ayana; Nurpeissova, Arailym; Rachid Babaa, Moulay; Bakenov, Zhumabay (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)
    This work investigates a combined LTO/Si composite anode in a LIB with excellent electrochemical performance. The LTO/Si system is dispersed in cyclized polyacrylonitrile (c-PAN) polymer matrix, which is widely used as an ...
  • N-type doped amorphous Si thin film on a surface of rough current collector as anode for Li-ion batteries [Article] 
    Mukanova, Aliya; Nurpeissova, Arailym; Zharbossyn, Assem; Kim, Sung-Soo; Myronov, Maksym; Bakenov, Zhumabay (2018-12-31)
    Abstract In this study, we report on the preparation of n-type doped ∼ 400 nm thick amorphous Si thin film on a surface of 9µm rough current collector. The electrochemical cycling test of designed anodes revealed that Si ...
  • PHOTOTHERMAL EFFECTS AND HEAT CONDUCTION IN NANOGRANULAR SILICON FILMS 
    Kurbanova, Bayan A.; Mussabek, Gauhar K.; Timoshenko, Viktor Y.; Lysenko, Vladimir; Utegulov, Zhandos N. (MDPI, 2021-09-13)
    We present results on the photothermal (PT) and heat conductive properties of nanogranular silicon (Si) films synthesized by evaporation of colloidal droplets (drop-casting) of 100 ± 50 nm-sized crystalline Si nanoparticles ...
