Abstract
A method for the manufacture of a pyrolytic graphite with high crystallinity comprising the deposition of graphite directly onto a crystalline catalytic substrate by thermal decomposition of a carbon-containing material at a temperature of 1000.degree. C. or less, the pyrolytic graphite having interlayer spacing in a limited range and a c-axis orientation of carbon layers perpendicular to the surface of the substrate. An electrode with graphite as an active material and a crystalline metal electrode substrate as a current collector unified, the graphite being pyrolytic graphite that is deposited on the crystalline metal electrode substrate with catalytic properties so as to cover the crystalline metal electrode substrate by the above-mentioned method.
