Anodes comprising germanium for lithium-ion devices |
摘要 |
An anode material for a lithium ion device includes an active material including germanium and boron. The weight percentage of the germanium is between about 45 to 80 weight % of the total weight of the anode material and the weight percentage of the boron is between about 2 to 20 weight % of the total weight of the anode material. The active material may include carbon at a weight percentage of between 0.5 to about 5 weight % of the total weight of the anode material. Additional materials, methods of making and devices are taught. |

1. An anode material for a lithium ion device, comprising:
an active material comprising germanium nano-particles having a particle size of 20 to 100 nm, boron carbide nano-particles having a particle size of 20 to 100 nm and tungsten carbide nano-particles having a particle size of 20 to 60 nm, wherein the weight percentage of the germanium is between 5 to 80 weight % of the total weight of the anode material, the weight percentage of boron in the anode material is between 2 to 20 weight % of the total weight of the anode material and the weight percentage of tungsten in the anode material is between 5 to 20 weight % of the total weight of the anode material. |
