Abstract:
An anode material for a lithium ion device includes an active material including silicon nanoparticles and boron carbide nanoparticles. The boron carbide nanoparticles are at least one order of magnitude smaller than the silicon nanoparticles. The weight percentage of the silicon is between about 4 to 35 weight % of the total weight of the anode material and the weight percentage of the boron carbide is between about 2.5 to about 25.6% of the total weight of the anode material. The active material may include carbon at a weight percentage of between 5 to about 60 weight % of the total weight of the anode material. Additional materials, methods of making and devices are taught.
