Cr[sub 1−x]Fe[sub x]N (0≦x≦1) Ternary Transition-Metal Nitrides as Anode Materials for Lithium-Ion Batteries

Lithium electrochemistry of ternary transition-metal nitrides has been investigated for the first time. The reversible capacities of ternary transition-metal nitrides were all above , and their electrodes overcame the large polarization of CrN electrode and the bad cyclic stable of FeN electrode, which made them promising candidates for lithium-ion battery anode. Our results demonstrated that the reversible formation and decomposition of could be driven by nanosized metal Fe or Cr.
