Graphite material and production method thereof, negative electrode material for lithium ion secondary battery, negative electrode for lithium ion secondary battery, and lithium ion secondary battery |
| abstract |
Disclosed is a graphite material wherein protrusions having a height of not less than 1 µm are sprinkled. This graphite material is suitable for negative electrodes and negative electrode materials for lithium ion secondary batteries. By using such a negative electrode, there can be obtained a lithium ion secondary battery having high discharge capacity, high initial charge/discharge efficiency, excellent high-rate charge/discharge characteristics and excellent cycle characteristics. Also disclosed is a method for simply producing such a graphite material at low cost. |
