COMPOSITE ELECTRODE MATERIAL

摘要

The invention relates to a composite material comprising carbon fibers and complex oxide particles, wherein the carbon fibers and the complex oxide particles have a carbon coating on at least part of their surface, said carbon coating being a non powdery coating The material is prepared by a method comprising mixing a complex oxide or precursors thereof, an organic carbon precursor and carbon fibers, and subjecting the mixture to a heat treatment in an inert or reducing atmosphere for the decomposition of the precursors The material is useful as the cathode material in a battery.
