MANUFACTURING METHOD OF ELECTRODE MATERIAL

摘要

A method of manufacturing a composite materials in which a carbon material and a metal compound can maintain a nanosized form as a final product is realized, and a method for manufacturing a superior electrode material is provided. A metal compound precursor is formed from a metal compound material source, and a mixture of the metal compound precursor and a carbon material is calcinated. In the treatment to form the precursor, a treatment of absorbing one of the metal compound material sources to the functional group of the carbon material and a treatment of producing on the carbon material a treatment of reacting the remaining material source of the adsorbed metal compound material source on the carbon material to produce a metal compound precursor are performed in separate steps.

1. A method for manufacturing an electrode material consisting of a composite material of a metal compound capable of occluding and releasing lithium supported on a carbon material, comprising:
a first mechanochemical treatment of dispersing a starting material for a metal compound capable of occluding and releasing lithium and a carbon material by applying sheer stress and centrifugal force in a rotating reactor, a second mechanochemical treatment of further applying sheer stress and centrifugal force in the reactor after the first mechanochemical treatment to allow production of the metal compound precursor from the starting material, and a calcination treatment for heating a mixture obtained by the second mechanochemical treatment.
