Abstract
An anode material made from nanoparticles, said anode material including a homogeneous mixture of lithium-alloying nanoparticles with active support matrix nanoparticles, is provided. The active support matrix nanoparticle is a compound that participates in the conversion reaction of the lithium battery. The compound is preferably a transition metal compound, with said compound including a nitride, carbide, oxide or combination thereof. An electrode manufactured from the anode material preferably has a porosity of between 5 and 80% and more preferably has a porosity between 10 and 50%. The anode material nanoparticles preferably have a mean linear dimension of between 2 and 500 nanometers, and more preferably have a mean linear dimension of between 2 and 50 nanometers.
