Abstract:
Methods for making anodes for lithium ion devices are provided. The methods include milling germanium powder, carbon, and boron carbide powder to form a nano-particle mixture having a particle size of 20 to 100 nm; adding an emulsion of tungsten carbide nano-particles having a particle size of 20 to 60 nm to the mixture to form an active material; and adding a polymeric binder to the active material to form the anode, wherein the weight percentage of the germanium in the anode is between 5 to 80 weight % of the total weight of the anode, the weight percentage of boron in the anode is between 2 to 20 weight % of the total weight of the anode and the weight percentage of tungsten in the anode is between 5 to 20 weight % of the total weight of the anode.
