abstract = {We report evidence for the electrochemical activity of
transition-metal carbodiimides versus lithium and sodium. In
particular, iron carbodiimide, FeNCN, can be efficiently
used as negative electrode material for alkali-metal-ion
batteries, similar to its oxide analogue FeO. Based on 57Fe
Mössbauer and infrared spectroscopy (IR) data, the
electrochemical reaction mechanism can be explained by the
reversible transformation of the Fe−NCN into Li/Na−NCN
bonds during discharge and charge. These new electrode
materials exhibit higher capacity compared to
well-established negative electrode references such as
graphite or hard carbon. Contrary to its oxide analogue,
iron carbodiimide does not require heavy treatments (such as
nanoscale tailoring, sophisticated textures, or coating) to
obtain long cycle life with current density as high as
9 A g−1 for hundreds of charge–discharge cycles.
Similar to the iron compound, several other transition-metal
carbodiimides Mx(NCN)y with M=Mn, Cr, Zn can cycle
successfully versus lithium and sodium. Their
electrochemical activity and performance open the way to the
design of a novel family of anode materials.},
