Abstract
The present invention can provide a composite negative electrode active material including a fused matter of a graphite material and a graphitizable carbon material undergoing graphitization. Such a composite negative electrode active material is prepared by heating a mixture of a graphite material and a graphitizable carbon material undergoing graphitization at 700° C. to 1300° C., and crushing the obtained fused matter. The use of the composite negative electrode active material makes it possible to provide a non-aqueous electrolyte secondary battery being excellent in output-input characteristics and having a high energy density and a long life.
