Electrospun Lotus Root-like CoMoO4@Graphene Nanofibers as High-Performance Anode for Lithium Ion Batteries

Lotus root-like CoMoO4@graphene nanofibers(CoMoO4@G NFs) was prepared by electrospinning along with post heat treatment, and used as high-performance anode for lithium ion batteries (LIBs). Compared with the pure CoMoO4 NFs, the prepared lotus root-like CoMoO4@G NFs electrode displays higher reversible capacity of 735 mA h g (1) at 100 mA g (1), better rate capability and cycling stability (capacity retains 80% based on the second cycle even after 200 cycles,). These results highlight the importance of combination of conductive graphene nanosheets with multi-level porous CoMoO4 NFs for high-performance LIBs. (C) 2016 Elsevier Ltd. All rights reserved.
