<P>PROBLEM TO BE SOLVED: To achieve a graphite-based hydrogen-occluding material which is lightweight, can be repeatedly used and easily produced, and to achieve a method for producing the same. <P>SOLUTION: The graphite-based hydrogen-occluding material comprises a graphite aggregate in which nanostructured graphite with crystallites having a size of 1-40 nm is aggregated. The graphite aggregate has an average particle size of 1-60 μm, a specific surface area of 300 m<SP>2</SP>/g or more, an average pore radius of 5.5 nm or less, and an interlayer distance of 0.3360-0.3385 nm. <P>COPYRIGHT: (C)2004,JPO |
