Effect of graphene nanosheets on electrochemical performance of Li4Ti5O12 in lithium-ion capacitors

Lu, Chengxing; Wang, Xin; Zhang, Xin; Peng, Huifen; Zhang, Yongguang; Wang, Gongkai; Wang, Zhenkun; Cao, Guanlong; Umirov, Nurzhan; Bakenov, Zhumabay (Ceramics International, 2017-06-01)

Abstract In order to improve the electrochemical performance of lithium titanium oxide, Li4Ti5O12 (LTO), for the use in the lithium-ion capacitors (LICs) application, LTO/graphene composites were synthesized through a solid ...
Effect of VO43− substitution for PO43− on electrochemical properties of the Li3Fe2(PO4)3 cathode materials

Yang, Yonggang; Zhang, Yongguang; Hua, Zhengshen; Wang, Xin; Peng, Huifen; Bakenov, Zhumabay (Electrochimica Acta, 2016-11-20)

Abstract In this research, VO43− substitution was used to improve electrochemical properties of the Nasicon Li3Fe2(PO4)3 cathode material. The VO43− substitution resulted in formation of a homogeneous compound Li3Fe2(PO4)3-x(VO4)x ...
Facile Synthesis of SiO2@C Nanoparticles Anchored on MWNT as High-Performance Anode Materials for Li-ion Batteries

Zhao, Yan; Liu, Zhengjun; Zhang, Yongguang; Mentbayeva, Almagul; Wang, Xin; Maximov, M. Yu.; Liu, Baoxi; Bakenov, Zhumabay; Yin, Fuxing (Nanoscale Research Letters, 2017)

Carbon-coated silica nanoparticles anchored on multi-walled carbon nanotubes (SiO2@C/MWNT composite) were synthesized via a simple and facile sol-gel method followed by heat treatment. Scanning and transmission electron ...
Well-dispersed sulfur anchored on interconnected polypyrrole nanofiber network as high performance cathode for lithium-sulfur batteries

Yin, Fuxing; Liu, Xinyi; Zhang, Yongguang; Zhao, Yan; Menbayeva, Almagul; Bakenov, Zhumabay; Wang, Xin (Solid State Sciences, 2017-04-01)

Abstract Preparation of novel sulfur/polypyrrole (S/PPy) composite consisting well-dispersed sulfur particles anchored on interconnected PPy nanowire network was demonstrated. In such hybrid structure, the as-prepared PPy ...
ZnO Nanorods Grown Directly on Copper Foil Substrate as a Binder-Free Anode for High Performance Lithium-Ion Batteries

Huang, Lanyan; Wang, Xin; Yin, Fuxing; Zhang, Yongguang; Gao, Jinwei; Liu, Junming; Zhou, Guofu; Bakenov, Zhumabay (International Journal of ELECTROCHEMICAL SCIENCE. www.electrochemsci.org, 2016-09-06)

ZnO nanorods directly grown on copper foil substrate were obtained via hydrothermal method without using templates. Structure and morphology of the as-prepared ZnO nanorods were characterized by X-ray diffraction, scanning ...
