ABSTRACT:
An impermeable electrode for batteries, with an impermeable conductive layer of graphite, which is deposited from a suspension comprising graphite at a concentration between 1 and 50 g/l in an organic solvent on a substrate by immersion for a given length of time of, for example, approximately 10 to 60 seconds and wherein, after the deposition, the substrate with the layer of graphite is dried at a temperature between approximately 80 and 150° C. for a given length of time of, for example, approximately 1 minute and, after the drying, is heat-treated at a temperature between approximately 200 and 450° C. for a given length of time of, for example, approximately 5 to 60 minutes.
