NOVELTY - The electrical storage device (10) has a positive electrode (1) that is formed with a carbonaceous material. A mean area of carbonaceous material of each amorphous portion portions which are distributed to a plane is formed more than 1.5 nm2. A ratio of carbonaceous material with respect to amorphous portions and crystalline portion is formed 30% or more than a total area of amorphous portion portions and a crystalline portion. A negative electrode (4) is formed with the carbonaceous material in which a lithium ion is occluded previously.    USE - Electrical storage device used as storage battery combined with new energy systems, storage battery for motor vehicle, hybrid vehicle, and electric vehicle, as well as used in portable apparatuses such as mobile telephone, notebook personal computer, solar cell and wind power generation.    ADVANTAGE - The quantity of intercalation of an anion or a cation can be increased, so that electrical storage device is provided with effective ability to achieve a high capacitation. Since electrolytic ion intercalates preferentially and easily in the amorphous portion of carbonaceous material when the carbonaceous material is used as an electrode, the amount of intercalation in carbonaceous material can be increased, and the discharge capacity of an electrical storage apparatus can be improved.    DETAILED DESCRIPTION - The carbonaceous material of negative electrode provided with graphite or difficultly-graphitizing carbon and is obtained by making a negative electrode and a lithium metal to react electrochemically. The carbonaceous material of the positive electrode is provided with graphite. The triethylmethylammonium tetrafluoroborate is used as electrolyte in a nonaqueous electrolyte. A liquid containing a cyclic carbonate and a linear carbonate, or fluorine containing organic solvent is used as solvent in the non-aqueous electrolyte.
