Transition-Metal Carbodiimides as Molecular Negative Electrode Materials for Lithium- and Sodium-Ion Batteries with Excellent Cycling Properties

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 M?ssbauer 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 9A 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.

Zinc cyanamide, Zn(CN2)

Single crystals of the title compound have been grown by annealing microcrystalline zinc cyanamide at 843 K in silver crucibles. Zn(CN2) crystallizes as colourless prisms. The crystal structure is composed of corner-linked ZnN4/2 tetrahedra. Carbon and nitrogen form (CN2)2- dumb-bells with the C atom on a twofold axis. Nitrogen is approximately trigonally planar, coordinated by two Zn atoms and one C atom.

Preparation method and application of zinc carbodiimide material

The invention provides a preparation method of a zinc carbodiimide material. The method comprises the following steps: 1) uniformly mixing octan zinecnaty and oxalic acid, grinding, and drying to obtain a zinc oxalate precursor; 2) uniformly mixing the zinc oxalate precursor and melamine, grinding, calcining and cooling, and grinding again, thereby obtaining the needed zinc carbodiimide material.The invention further provides application of the zinc carbodiimide material serving as a photocatalyst in degradation of environmental pollutants and a method for degrading the environmental pollutants.
