Application:The spherical graphite can be used in the many kinds of batteries,such as the cell atteries,the laptop batteries,
The spherical graphite is produced carefully yo adop series of unique technologies by our professinal staffs. It's the ideal materials as the negative pole materials of the lithium batteries.
Production Features:
| 1,Better crystallinity with the productions | 2,High spherify |
| 3,Less particle surface defect; | 4,High tap density; |
| 5,Low surface area; | 6,Stable properties; |
| 7,The uniform distribution of the particle size. | |
Application:The spherical graphite can be used in the many kinds of batteries,such as the cell atteries,the laptop batteries,the MP3 batteries,the digital camera batteries,the model airplane batteries,the li-ion batteries,the li-ion power batteries and so on.
