Prussian blue analogues: a new class of anode materials for lithium ion batteries

Herein, we demonstrate that nanoparticles of cobalt hexacyanocobaltate and manganese hexacyanocobaltate, typical Prussian blue analogues with the chemical formula M₃^II[Co^III(CN)₆]₂·nH₂O (M = Co, Mn), can be operated as novel battery anodes in an organic liquid-carbonate electrolyte.
