CARBON BLACK AND RECHARGEABLE BATTERY USING SAME

摘要

Provided are: carbon black having excellent conductivity-imparting performance and dispersibility; and a rechargeable battery using same. This carbon black has a specific surface area (SSA) according to JIS K6217-2:2001 of 80-150m2/g, DBP absorption (DBP) according to JIS K6217-4:2008 of at least 150ml/100g, a ratio DBP/CDBP of DBP absorption (DBP) to compression DBP absorption (CDBP) according to JIS K6217-4:2008 of at least 1.50. It is preferable that the ratio SSA/CSSA of specific surface area (SSA) to specific surface area after being compressed 4 times at 165MPa (CSSA) be at least 0.90.
