Abstract
A method for the manufacture of a pyrolytic graphite with high crystallinity comprising the deposition of graphite directly onto a catalytic substrate by thermal decomposition of a carbon-containing material at low temperatures. An electrode with graphite as an active material and an electrode substrate as a current collector unified, said graphite being pyrolytic graphite that is deposited on a metal electrode substrate with catalytic properties so as to cover said metal electrode substrate by the method. A battery has a pair of positive and negative electrodes, at least one of which is made of graphite as its electrode active material.
