Title:
CARBON BLACK FOR ELECTRODE AND ELECTRODE SLURRY
Document Type and Number:
WIPO Patent Application WO/2018/221632
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a carbon black for an electrode which is capable of imparting sufficient conductivity when added even in small amounts, has good dispersibility in an electrode slurry, and is capable of realizing excellent battery performance. This carbon black for an electrode has a BET specific surface area of 700 to 1,500 m2/g and includes an acidic functional group in the amount of 0.15 to 2.0 mmol/g. An electrode can be produced by forming an active substance layer on a collector using an electrode slurry that contains: the carbon black for an electrode; an electrode active substance; and a binder resin.
