Patent attributes
A method for manufacturing composites in which the nanosize of a carbon material and a metal compound can be maintained as the final product is realized to provide a superior electrode material. A treatment of increasing the functional groups possessed by a carbon material is performed in advance. Then, a metal compound precursor is supported on a carbon material by separately performing a treatment of adsorbing one of source materials of the metal compound to the functional groups of the carbon material having increased functional groups and a treatment of reacting the adsorbed source material of the metal compound with the rest of the source materials on the carbon material to produce a metal compound precursor on the carbon material. Finally, a lithium source is introduced and calcined.
