PROBLEM TO BE SOLVED: To provide a carbon black composite having excellent electroconductivity-imparting ability. SOLUTION: The carbon black composite is prepared by linking fibrous carbon with a carbon black, and has≤1.0 mass% of the ash content defined by JIS K 1469. Preferably, the content of the fibrous carbon is 1-50 mass%, and the average diameter of the fibrous carbon is≤100 nm. The carbon black is preferably acetylene black. An electrode for a battery and an active material for the battery containing the carbon black composite are also provided. COPYRIGHT: (C)2010,JPO&INPIT |
