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 ...
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 ...
In situ sol-gel synthesis of ultrafine ZnO nanocrystals anchored on graphene as anode material for lithium-ion batteries

Li, Haipeng; Wei, Yaqiong; Zhang, Yongguang; Zhang, Chengwei; Wang, Gongkai; Zhao, Yan; Yin, Fuxing; Bakenov, Zhumabay (Ceramics International, 2016-08-01)

Abstract Ultrafine ZnO nanocrystals anchored on graphene were synthesized by a facile and highly efficient in situ sol-gel method. Uniform ZnO nanocrystals with an average size of 9.3nm were well dispersed on graphene ...
