PURPOSE:To obtain a positive electrode material having large energy density and making internal resistance low by containing a graphite vapor-deposition layer directly covered from a vapor phase on a carbon fiber base material and a guest compound intercalated in this vapor-deposition layer. CONSTITUTION:A carbon fiber base material 1, a graphite vapor-deposition layer 2 directly covered from a vapor phase on the base material 1, and a guest compound intercalated in the vapor-deposition layer 2 are contained. The vapor-deposition layer 2 directly covered from the vapor phase on the base material 1 grows and it further grows by heat treatment. By intercalating a guest compound, an electrochemical reaction area is enlarged, and a positive electrode material having high energy density is obtained. A fibrous graphite intercalation compound 4 has good electrocondcutivity and makes internal resistance low. |
