| 摘要 |
This invention relates with the carbon powder which is characterized to enhance the adhesive strength and the electrophretic nature to the electrode by including one or more than two of sulfur, nitrogen, boron, phosphorus, and fluorine, with 1 - 20wt% of oxygen. The second battery, which is added with the secondary battery activator comprising this surface modified carbon powder or with this surface modified carbon, has a long cell life, and when this carbon powder is added, the second battery, which cannot be charged/discharged, can be also regenerated. <IMAGE> |
