▎ 摘　　要

A nanocomposite of potassium manganese ferrocyanide and graphene (12% C, 88% K1.8Mn1.1Fe(CN)(6)center dot 0.27H(2)O) was prepared by ball milling of graphene oxide powder and nanoparticles of manganese-iron Prussian Blue. It exhibits enhanced electrochemical performance compared to pure Prussian Blue with a specific capacity of 150 mAhg(-1) at average 3.8 V vs. Li+/Li and a good cyclability. The nanocomposite can be considered as competitive to standard cathode materials of present rechargeable lithium ion batteries like cobalt oxide, iron phosphate or NMC. (C) 2013 Elsevier B.V.
