Abstract
Described is an anode material which is a transition metal nitride or carbide in form of nanoparticles, preferably a nitride or carbide with one nitrogen or carbon per metal, and especially a nitride or carbide having rock salt structure. A preferred anode material is vanadium nitride, in particular carbon coated vanadium nitride having a mean particle size of <500 nm. Embedded in an electrically conducting environment, such nanoparticulate material, in particular the vanadium nitride shows exceptional good charging-discharging cycle stability.
