Abstract

Graphene-NiFe2O4-carbon nanocomposites with a sandwich structure are synthesized via the hydrothermal growth of NiFe2O4nanoparticles on graphene sheets, followed by carbon coating. As a promising anode material for Li ion batteries, the nanocomposites deliver exceptional cycle stability of 1195 mA h g-1after 200 cycles measured at 500 mA g-1. This value is among the highest reported so far for anodes containing similar NiFe2O4nanoparticles. The synergy arising from the conductive graphene substrate, the well-dispersed, ultrafine NiFe2O4nanoparticles and the protective carbon layer sustaining the sandwich together is responsible for this trait.
