通过简单的超声辅助共沉淀法处理尺寸类似于10 nm的单分散Fe 3 O 4纳米颗粒，与氧化石墨烯机械混合，并热还原以形成磁铁矿-石墨烯复合材料。Fe 3 O 4-石墨烯纳米复合材料的电化学表征显示出超过1200 mA h g（-1）的优异容量，以及在至少1000次循环的高电流循环期间的优异稳定性。
Monodispersed Fe3O4 nanoparticles of size similar to 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 Fe3O4-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.
