ABSTRACT:
A cathode current collector/container for use in an electrochemical battery cell, e.g., a Na/S battery cell, which includes an advantageously porous graphite first layer and a molybdenum second layer securely bonded to the graphite first layer, preferably by means of a chemical vapor deposition process. In a preferred embodiment, the cathode current collector/container further includes a third layer constituted of a structurally rigid, electrically conductive material, e.g., tantalum, securely bonded to the molybdenum second layer, preferably by means of a chemical vapor deposition process. Additionally, the cathode current collector/container may further include a protective coating of sealant material, e.g., pyrolitic graphite or carbon, deposited at least partially within pores of the porous graphite constituting the first layer. The cathode current collector/container may be embodied in either a tubular or planar structural configuration.
In the presently contemplated best mode of the present invention, the cathode current collector/container is a tubular structure comprised of a porous graphite tube having a thickness of less than approximately 10 mils; a molybdenum layer having a thickness within the range of approximately 3-10 mils, chemically vapor deposited on the inside of the graphite tube; and, a tantalum layer having a thickness within the range of approximately 8-12 mils, chemically vapor deposited on the molybdenum layer.
