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.
