Prussian blue analogues Mn[Fe(CN)₆]0.6667·nH₂O cubes as an anode material for lithium-ion batteries

In the present work, Prussian blue analogues, Mn[Fe(CN)6]0.6667·nH2O (Mn-PBA), were synthesized by a simple synthetic route and characterized by XRD, SEM, TEM, FTIR and TGA. When this material was firstly used as an anode for lithium-ion batteries, it exhibited a large capacity, good rate capability and cycling stability with a high Coulombic efficiency. For instance, a reversible capacity of 295.7 mA h g(-1) can be achieved after 100 cycles at 200 mA g(-1).
