Short communicationNanocomposite of manganese ferrocyanide and graphene: A promising cathode material for rechargeable lithium ion batteries

Add time:08/26/2019    Source:sciencedirect.com

A nanocomposite of potassium manganese ferrocyanide and graphene (12% C, 88% K1.8Mn1.1Fe(CN)6∙ 0.27H2O) 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.
