Abstract
An object of the present invention is to provide a carbon material for negative electrodes of non-aqueous secondary batteries having a high capacity, a high output, excellent cycle characteristics and a low irreversible capacity. The present invention relates to a carbon material for negative electrodes of non-aqueous secondary batteries, the carbon material comprising: (1) a composite carbon particles (A) containing elemental silicon, and (2) amorphous composite graphite particles (B) in which graphite particles (C) and amorphous carbon are composited.
