This invention relates with the carbon powder which is characterizednto enhance the adhesive strength and the electrophretic nature to thenelectrode by including one or more than two of sulfur, nitrogen, boron,nphosphorus, and fluorine, with 1 - 20wt% of oxygen. The second battery,nwhich is added with the secondary battery activator comprising this surfacenmodified carbon powder or with this surface modified carbon, has a long cellnlife, and when this carbon powder is added, the second battery, which cannotnbe charged/discharged, can be also regenerated. |
