Hydrothermal Synthesis of Multiwalled Carbon Nanotube-Zinc Manganate Nanoparticles as Anode Materials for Lithium Ion Batteries.

Abstract

Multiwalled carbon nanotube (MWCNT)-ZnMn2 O4 nanoparticles were fabricated by a hydrothermal method without further thermal treatment. The morphology and microstructure were investigated by X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy and the Brunauer-Emmett-Teller method. Owing to the synergistic effect and strongly coupled interaction between the MWCNTs and ZnMn2 O4 nanoparticles, the MWCNT-ZnMn2 O4 composite material exhibited a higher specific capacity of 809 mA h g-1 , good rate capability and stable cycling performance compared to both pristine ZnMn2 O4 nanoparticles and MWCNTs, indicating it to be a promising anode material for lithium ion battery applications.
