GRAPHITE MATERIAL, CARBONACEOUS MATERIAL FOR BATTERY ELECTRODES, AND BATTERIES |
摘要 |
Provided are a graphite material suitable as an electrode material for nonaqueous electrolyte secondary batteries, a carbonaceous material for battery electrodes, and secondary batteries which exhibit excellent charge-discharge cycle characteristics and excellent severe-current-load characteristics. A graphite material which has specific sizes of optically anisotropic and isotropic structures, a specific content ratio between both structures, and various orientation of crystallization; and a carbonaceous material for battery electrodes which is made using the graphite material and which exhibits a large discharge capacity and a small irreversible capacity with the severe-current-load characteristics and cycle characteristics being kept at high levels. |
