Biomass Waste Inspired Highly Porous Carbon for High Performance Lithium/Sulfur Batteries

Zhao, Yan; Ren, Jun; Tan, Taizhe; Babaa, Moulay-Rachid; Bakenov, Zhumabay; Liu, Ning; Zhang, Yongguang (MDPI, 2017-09-06)

The synthesis of highly porous carbon (HPC) materials from poplar catkin by KOH chemical activation and hydrothermal carbonization as a conductive additive to a lithium-sulfur cathode is reported. Elemental sulfur was ...
Polyacrylonitrile-Nanofiber-Based Gel Polymer Electrolyte for Novel Aqueous Sodium-Ion Battery Based on a Na4Mn9O18 Cathode and Zn Metal Anode

Zhang, Yongguang; Bakenov, Zhumabay; Tan, Taizhe; Huang, Jin (MDPI, 2018-08-02)

A gel polymer electrolyte was formed by trapping an optimized Na+/Zn2+ mixed-ion aqueous electrolyte in a polyacrylonitrile nanofiber polymer matrix. This electrolyte was used in a novel aqueous sodium-ion battery (ASIB) ...
Synthesis of a Flexible Freestanding Sulfur/Polyacrylonitrile/Graphene Oxide as the Cathode for Lithium/Sulfur Batteries

Peng, Huifen; Wang, Xiaoran; Zhao, Yan; Tan, Taizhe; Bakenov, Zhumabay; Zhang, Yongguang (Polymers, 2018-04)

Rechargeable lithium/sulfur (Li/S) batteries have received quite significant attention over the years because of their high theoretical specific capacity (1672 mAh g􀀀1) and energy density (2600 mAh g􀀀1) which has led ...
Synthesis of Core-Shell Carbon Encapsulated Fe2O3 Composite through a Facile Hydrothermal Approach and Their Application as Anode Materials for Sodium-Ion Batteries

Zhang, Yongguang; Bakenov, Zhumabay; Tan, Taizhe; Huang, Jin (Metals, 2018-06)

Carbon encapsulated Fe2O3 nanoparticles (C@Fe2O3) were successfully synthesized via a facile and environmentally friendly hydrothermal method and prototyped in anode materials for sodium ion batteries (SIBs). High-resolution ...
Synthesis of ZnO/Polypyrrole Nanoring Composite as High-Performance Anode Materials for Lithium Ion Batteries

Li, Haipeng; Yang, Shuang; Zhao, Yan; Tan, Taizhe; Wang, Xin; Bakenov, Zhumabay (Hindawi, 2019)

ZnO has attracted considerable attention as electrode material in lithium-ion battery (LIB) due to its theoretically high capacity. However, poor electronic conductivity and huge volumetric changes during cycling limit its ...
Three-Dimensionally Hierarchical Graphene Based Aerogel Encapsulated Sulfur as Cathode for Lithium/Sulfur Batteries

Li, Haipeng; Sun, Liancheng; Wang, Zhuo; Zhang, Yongguang; Tan, Taizhe; Wang, Gongkai; Bakenov, Zhumabay (MDPI, 2018-01-26)

A simple and effective method was developed to obtain the electrode for lithium/sulfur (Li/S) batteries with high specific capacity and cycling durability via adopting an interconnected sulfur/activated carbon/graphene ...
