Abstract:
Monodispersed Fe(3)O(4) nanoparticles of size ∼10 nm were processed by a simple ultrasonic assisted co-precipitation method, mechanically mixed with graphene oxide, and thermally reduced to form a magnetite-graphene composite. Electrochemical characterization of the Fe(3)O(4)-graphene nanocomposites showed excellent capacity in excess of 1200 mA h g(-1), and exceptional stability during high current cycling for at least 1000 cycles.
