An introduction of new nanostructured Zn0.29V2O5 cathode material for lithium ion battery: a detailed studies on synthesis, characterization and lithium uptake

Abstract

The present work demonstrates the introduction of zinc and vanadium based new and novel cathode material for lithium ion secondary battery. Herein, the newly identified Zn0.29V2O5 was synthesized by sucrose assisted nitrate decomposition technique where the carbonization and generation of the enormous amount of heat and gaseous products, during the course of preparation, leads to the formation of unique layered mesoporous Zn0.29V2O5 nanostructures with high purity in a short period. Due to the synergetic effect of nano-engineering and addition of Zn2+ into V2O5 together with mesopores, the nanostructured Zn0.29V2O5 delivers high discharge capacity of 460 mAhg−1 after 100 cycles at 0.1 C. Further, the result shows that the unique nanostructured Zn0.29V2O5 not only favour charge and mass transfer but also effectively mitigates volume expansion and thereby exhibit high rate capability and long cycling performance.
