Metal-Organic Framework Fabricated V₂ O₅ Cathode Material for High-Performance Lithium-Ion Batteries

In this article, oval-shaped V₂ O₅ nanoparticles were hydrothermally synthesized using a metal-organic framework (MOF), which was then followed by calcination under an air atmosphere. The obtained sample was characterized through various characterization techniques to determine the sample purity and the structural and morphological details. Since V₂ O₅ possesses a layered crystal structure, it exhibits promising electrochemical performances as a cathode material for lithium-ion battery applications. However, poor cycling and inferior rate capabilities are the major issues that limit its application. Thus, a strategy to fabricate unique oval-shaped V₂ O₅ nanoparticles was employed here to improve electrochemical performances using an MOF, which acts as a template and provides a skeleton for the growth of a novel nanostructure. It is believed that the oval-shaped morphology is beneficial to achieving better electrochemical results due to the large surface area and the existence of numerous channels for lithiation and de-lithiation. The obtained electrochemical result reveals that the V₂ O₅ electrode can be considered a prominent cathode material for next-generation lithium-ion battery applications.
