Hydrothermal Preparation of Homogeneous Cobalt Oxide Nanomaterials as Stable Anodes for Superior Lithium Ion Batteries

In this study, uniform Co3O4 nanoparticles are prepared via a simple and facile hydrothermal synthesis without calcination treatment. When the nanomaterials investigated as anodes for lithium ion batteries, good electrochemical property is achieved. Particularly, reversible capacity of as-synthesized nanoparticle has significant growth from 383 mAh g−1 initial cycle to 471 300th at 2 A g−1. Moreover, when it recovers 50 mA after different current densities, superior 695 can be reached. Such favorable properties will make as-obtained have application prospect anode material batteries.
