摘要
A method of continuously manufacturing thin porous conductive strips, the strips including at least one layer based on a substance which contains carbon and a binder, the method comprising the successive steps of: preparing a very dilute aqueous dispersion of carbon or graphite fibers; adding an aqueous binder emulsion to the dispersion; initiating precipitation of a part of the binder onto the fibers; spreading the mixture in the form of a layer (1,2); removing at least some of the water from the mixture (3); drying the mixture (4,5,6,7); and setting the layer to the required thickness (8) which may be less than a few tens of microns.
