ABSTRACT:
A novel carbonaceous material having a unique periodical annular electronic surface structure as examined by means of a scanning tunnel microscopy can be obtained by the method comprising the steps of: (a) forming a layer of a carbonaceous material having a curved configuration by the method of vapor-phase deposition of a carbonaceous material; and (b) subjecting the vapor-phase deposited layer of the carbonaceous material to a heat treatment at a temperature of 1500 K or higher in a non-oxidizing atmosphere. The novel carbonaceous material is useful for carbon electrodes of various batteries.
