Abstract
A cathode material is fabricated using two binder compounds, polyethylene oxide and acrylic resin, which react during processing to achieve enhanced bonding. The cathode material is formed by dissolving acrylonitril resin within the acetonitrile solvent. Polyethylene oxide powder is added yielding a homogenous solution. A powder mix containing a carbon material, such as high surface area carbon powder, and an active cathode compound, such as polycarbon monoflouride, is added to the binder mixture to produce a slurry. In one embodiment, the slurry is heated to evaporate the solvents, yielding a thin flexible cathode material for mounting to an expanded screen current collector. In an alternative embodiment, the slurry is spread directly onto a foil current collector. The solvents thereafter evaporate from the slurry yielding excellent mechanical and electrical coupling between the active cathode compound and the current collector. The resulting cathode structure and a lithium anode structure are mounted to opposing sides of a polymeric separator for use within an electrochemical cell of an implantable medical device.
