  • Electrically Conductive Corrosion Resistant Bodies of Low Permeability
    Publication number: 20240001660
    Abstract: An electrically conductive, corrosion resistant carbon-based sheet with low permeability to liquids and gases and a method for its manufacture. A multilayer laminate consisting of polymeric film laminated with expanded graphite foil is produced by compressing the layers under heated conditions. The resulting laminate can be used to produce a current collector or a bipolar layer in an electrochemical cell.

  • BIPOLAR STRUCTURES FOR USE WITH ELECTROCHEMICAL DEVICES, AND ASSOCIATED SYSTEMS AND METHODS
    Publication number: 20230253677
    Abstract: Disclosed herein are polymer conductive films for use with electrochemical devices. An exemplary electrochemical device can include an anode, a cathode, and a bipolar structure disposed between the anode and cathode. The bipolar structure includes a film having a plurality of conductive particles and a plurality of non-conductive polymers, wherein the polymers are integrated with the particles such that the film is non-porous and substantially compositionally homogeneous along a length and/or thickness of the film.

  • Process for the manufacture of carbon sheet for an electrode
    Patent number: 9251969
    Abstract: A method of making a single carbon sheet for an electrode includes mixing activated carbon; adding a dispersion comprising a PTFE binder and water to the activated carbon to form a mixture; adding the mixture to a jet mill, and fibrillating the PTFE binder; and feeding the mixture with fibrillated PTFE to a roll mill to form a single carbon sheet in a single pass.
