New fabrication methods for electrodes in lithium-ion batteries

In the proposed program, Powdermet, Inc./Eagle-Picher Technologies, LLC, will demonstrate fabricating a novel anode for use in rechargeable lithium-ion battery systems. This technology could possible replace existing silver oxide/zinc battery technologyused in launch vehicle applications due to lower weight, volume, and cost. Specifically, Powdermet, Inc. will coat carbon microballoons with a layer of silver and carbon. These coated microballoons will then be added to a polymer matrix slurry andfabricated into anodes by Eagle-Picher Technologies, LLC. After anode fabrication, small capacity cells will be assembled and tested at Eagle-Picher Technologies' facilities. This proposed anode material should lead to an increased rate capability of theanode due to the inherent conductivity of silver matrixes with the carbon particulates, making lithium-ion batteries a more attractive option for launch vehicles, electric vehicles, and commercial satellite applications.The proposed lithium-ion batteryanodes will be applicable to other battery powered systems. This includes further aerospace (satellite power), commercial (geophysical exploration, underwater vehicles, underwater lighting, electric vehicle), and medical (neural stimulators, portableequipment power) applications.
