A simple approach to synthesize novel sulfur/graphene oxide/multiwalled carbon nanotube composite cathode for high performance lithium/sulfur batteries

Yuan, Guanghui; Zhao, Yan; Jin, Huafeng; Bakenov, Zhumabay (Ionics. Springer-Verlag Berlin Heidelberg 2016, 2016-04-30)

A sulfur/graphene oxide/multiwalled carbon nanotube (S/GO/MWNT) composite was synthesized via a simple ultrasonic mixing method followed by heat treatment. By taking advantage of this solution-based self-assembly ...

Corn stalk-derived activated carbon with a stacking sheet-like structure as sulfur cathode supporter for lithium/sulfur batteries

Yuan, Guanghui; Yin, Fuxing; Zhao, Yan; Bakenov, Zhumabay; Wang, Gongkai; Zhang, Yongguang (Ionics. DOI 10.1007/s11581-015-1528-6, 2015-09-02)

A novel stacking sheet-like carbon (SSC) has been synthesized by carbonizing the corn stalks and composited with sulfur to prepare a cathode for lithium/sulfur batteries. Scanning electronic microscopy observations ...
Enhanced cycle performance of Li/S battery with the reduced graphene oxide/activated carbon functional interlayer

Li, Haipeng; Sun, Liancheng; Zhang, Yongguang; Tan, Taizhe; Wang, Gongkai; Bakenov, Zhumabay (Journal of Energy Chemistry, 2017-11-01)

Abstract The high-energy lithium/sulfur (Li/S) battery has become a very popular topic of research in recent years due to its high theoretical capacity of 1672 mAh/g. However, the polysulfide shuttle effect remains of great ...
Preparation of novel network nanostructured sulfur composite cathode with enhanced stable cycle performance

Zhang, Yongguang; Zhao, Yan; Bakenov, Zhumabay; Konarov, Aishuak; Chen, P. (Journal of Power Sources, 2014-12-15)

Abstract In situ polymerization of acrylonitrile with nano-sulfur particles has been developed as a synthetic route to prepare sulfur/polyacrylonitrile (S/pPAN) composite as a cathode material for lithium/sulfur battery. ...
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 ...
