Micro-Spherical Sulfur/Graphene Oxide Composite via Spray Drying for High Performance Lithium Sulfur Batteries

Tian, Yuan; Sun, Zhenghao; Zhang, Yongguang; Wang, Xin; Bakenov, Zhumabay; Yin, Fuxing (Nanomaterials, 2018-01)

An efficient, industry-accepted spray drying method was used to synthesize microspherical sulfur/graphene oxide (S/GO) composites as cathode materials within lithium sulfur batteries. The as-designed wrapping of the ...
Nitrogen-doped carbon nanotubes coated with zinc oxide nanoparticles as sulfur encapsulator for high-performance lithium/sulfur batteries

Zhao, Yan; Liu, Zhengjun; Sun, Liancheng; Zhang, Yongguang; Feng, Yuting; Wang, Xin; Kurmanbayeva, Indira; Bakenov, Zhumabay (Beilstein Journal of Nanotechnology, 2018-06)

Nitrogen-doped carbon nanotubes coated with zinc oxide nanoparticles (ZnO@NCNT) were prepared via a sol–gel route as sulfur encapsulator for lithium/sulfur (Li/S) batteries. The electrochemical properties of the S/ZnO@NCNT ...
PROMOTING POLYSULFIDES REDOX CONVERSION BY SULFUR-DEFICIENT ZNS1 X HOLLOW POLYHEDRONS FOR LITHIUM-SULFUR BATTERIES

Gao, Wanjie; Jin, Qianwen; Liu, Yanyu; Zhang, Yongguang; Wang, Xin; Bakenov, Zhumabay (Materials & Design, 2021-08-21)

Lithium-sulfur (Li-S) batteries are deemed as the attractive systems for high-energy storage. However, the polysulfides shuttling with slow redox kinetics has seriously hindered their practical applications. Herein, ...
Ultra-fine zinc oxide nanocrystals decorated three-dimensional macroporous polypyrrole inverse opal as efficient sulfur hosts for lithium/sulfur batteries

Bakenov, Zhumabay; Zhang, Yongguang; Qiu, Weilong; Zhao, Yan; Wang, Xin (Elsevier, 2019-06-24)

Despite high theoretical capacity (1675 mAh g−1) and low cost of the lithium/sulfur (Li/S) batteries, their industrial road is impeded by rapid capacity loss and poor rate performances caused by the dissolution of lithium ...
