Electrospun 3D structured carbon current collector for Li/S batteries

Yerkinbekova, Yerkezhan; Kalybekkyzy, Sandugash; Mentbayeva, Almagul; Baikalov, Nurzhan; Kahraman, Memet Vezir; Bakenov, Zhumabay (The 8th International Conference on Nanomaterials and Advanced Energy Storage Systems; Nazarbayev University; National Laboratory Astana; Institute of Batteries, 2020-08)

Light weight carbon nanofibers (CNF) fabricated by a simple electrospinning method and used as a 3D structured current collector for a sulfur cathode. Along with a light weight, this 3D current collector allowed us to ...
Flexible S/DPAN/KB Nanofiber Composite as Binder-Free Cathodes for Li-S Batteries

Kalybekkyzy, Sandugash; Mentbayeva, Almagul; Kahraman, Memet Vezir; Zhang, Yongguang; Bakenov, Zhumabay (ELECTROCHEMICAL SOC INC, 2019-01-23)

Sulfur/dehydrogenated polyacrylonitrile/ketjen black (S/DPAN/KB) flexible nanofiber composite was prepared by electrospinning technique and tested as a freestanding cathode for high-performance flexible lithium/sulfur ...
PHOTO CROSSLINKED LIGNIN/PAN ELECTROSPUN SEPARATOR FOR SAFE LITHIUM ION BATTERIES

Yerkinbekova, Yerkezhan; Kalybekkyzy, Sandugash; Tolganbek, Nurbol; Kahraman, Memet Vezir; Bakenov, Zhumabay; Mentbayeva, Almagul (Scientific Reports, 2022)

A novel crosslinked electrospun nanofibrous membrane with maleated lignin (ML) and poly(acrylonitrile) (PAN) is presented as a separator for lithium-ion batteries (LIBs). Alkali lignin was treated with an esterification ...
