GRAPHITE/CARBON MIXED MATERIAL, CARBON MATERIAL FOR BATTERY ELECTRODES, AND BATTERY

摘要

The present invention provides a carbon material comprising a graphite material having diversity in the sizes of optical anisotropic structure and optical isotropic structure, the ratio thereof, and crystal direction, and a carbon material on the way to a graphitized structure of easily-graphitizable carbon. Use of the carbon material in the electrodes for the secondary battery can make the secondary battery be excellent in charge-discharge cycle characteristics and the large current load characteristics.
