3D graphene supported MoO2 for high performance binder-free lithium ion battery.

摘要: In this work, we report the synthesis of MoO2 nanoparticles grown on three dimensional graphene (3DG) via reduction α-MoO3 nanobelts through a facile chemical vapor deposition (CVD) approach under argon protection gas environment. approach, presence hydrophobic 3DG promoted Volmer-Weber growth (30-60 nm). The as-prepared MoO2-3DG nanocomposite was directly used as binder-free anode electrode for lithium ion batteries (LIBs) without additives and exhibited excellent electrochemical performance. It delivered high reversible capacities 975.4 mA h g(-1) 537.3 at current densities 50 1000 g(-1), respectively. Moreover, also showed an increased capacity from 763.7 to 986.9 after 150 discharge charge cycles density 200 g(-1). enhanced performance may be attributed synergistic effects layers. This CVD process presents feasible route large-scale production performance, environmentally friendly electrode. addition, has potential being utilized in other materials energy storage devices application.
