摘要
We report a γ-ray irradiation reduction method to prepare MnO/reduced graphene oxide (rCO) nanocomposite for the anode of lithium ion batteries. γ-Ray irradiation provides a clean way to generate homogeneously dispersed MnO nanoparticles with finely tuned size on rGO surface without the use of surfactant. The MnO/rGO composite enables a fully charge/discharge in 2 min to gain a reversible specific capacity of 546 (mA-h)/g which is 45 higher than the theoretical value of commercial graphite anode.
